It is in two files in the pub directory: -a compressed tar file popper-version.tar.Z and a Macintosh StuffIt archive -in BinHex format called MacPOP.sit.hqx. - - -Contents of the Distribution - -The distribution contains the following: - -+ All of the C source necessary to create the server program. - -+ A visual representation of how the POP system works. - -+ Reprints of RFC 1081 and RFC 1082. - -+ A HyperCard stack POP client implementation using MacTCP. - -+ A man page for the popper daemon. - -+ This guide. - - -Compatibility - -The Berkeley POP server has been successfully tested on the following -Unix operating systems: - -+ Berkeley Systems Distribution 4.3 - -+ Sun Microsystems Operating System versions 3.5 and 4.0 - -+ Ultrix version 2.3 - -The following POP clients operate correctly with the Berkeley POP server: - -+ The Berkeley HyperMail HyperCard stack for the Apple Macintosh - (distributed with the server). - -+ The Stanford University Macintosh Internet Protocol MacMH program. - -+ The Stanford University Personal Computer Internet Protocol MH - program. - -+ The mh version 6.0 programs for Unix. - - -Support - -The Berkeley POP server is not officially supported and is without any -warranty, explicit or implied. However, we are interested in your -experiences using the server. Bugs, comments and suggestions should be -sent electronically to netinfo@garnet.Berkeley.EDU. - - -Operational Characteristics - -The POP Transaction Cycle - -The Berkeley POP server is a single program (called popper) that is -launched by inetd when it gets a service request on the POP TCP port. -(The official port number specified in RFC 1081 for POP version 3 is -port 110. However, some POP3 clients attempt to contact the server at -port 109, the POP version 2 port. Unless you are running both POP2 and -POP3 servers, you can simply define both ports for use by the POP3 -server. This is explained in the installation instructions later on.) -The popper program initializes and verifies that the peer IP address is -registered in the local domain, logging a warning message when a -connection is made to a client whose IP address does not have a -canonical name. For systems using BSD 4.3 bind, it also checks to see -if a cannonical name lookup for the client returns the same peer IP -address, logging a warning message if it does not. The the server -enters the authorization state, during which the client must correctly -identify itself by providing a valid Unix userid and password on the -server's host machine. No other exchanges are allowed during this -state (other than a request to quit.) If authentication fails, a -warning message is logged and the session ends. Once the user is -identified, popper changes its user and group ids to match that of the -user and enters the transaction state. The server makes a temporary -copy of the user's maildrop (ordinarily in /usr/spool/mail) which is -used for all subsequent transactions. These include the bulk of POP -commands to retrieve mail, delete mail, undelete mail, and so forth. A -Berkeley extension also allows the user to submit a mail parcel to the -server who mails it using the sendmail program (this extension is -supported in the HyperMail client distributed with the server). When -the client quits, the server enters the final update state during which -the network connection is terminated and the user's maildrop is updated -with the (possibly) modified temporary maildrop. - - -Logging - -The POP server uses syslog to keep a record of its activities. On -systems with BSD 4.3 syslogging, the server logs (by default) to the -"local0" facility at priority "notice" for all messages except -debugging which is logged at priority "debug". The default log file is -/usr/spool/mqueue/POPlog. These can be changed, if desired. On -systems with 4.2 syslogging all messages are logged to the local log -file, usually /usr/spool/mqueue/syslog. - -Problems - -If the filesystem which holds the /usr/spool/mail fills up users will -experience difficulties. The filesystem must have enough space to hold -(approximately) two copies of the largest mail box. Popper (v1.81 and -above) is designed to be robust in the face of this problem, but you may -end up with a situation where some of the user's mail is in - - /usr/spool/mail/.userid.pop - -and some of the mail is in - - /usr/spool/mail/userid - -If this happens the System Administrator should clear enough disk space -so that the filesystem has at least as much free disk as both mailboxes -hold and probably a little more. Then the user should initiate a POP -session, and do nothing but quit. If the POP session ends without an -error the user can then use POP or another mail program to clean up his/her -mailbox. - -Alternatively, the System Administrator can combine the two files (but -popper will do this for you if there is enough disk space). - - -Debugging - -The popper program will log debugging information when the -d parameter -is specified after its invocation in the inetd.conf file. Care should -be exercised in using this option since it generates considerable -output in the syslog file. Alternatively, the "-t <file-name>" option -will place debugging information into file "<file-name>" using fprintf -instead of syslog. (To enable debugging, you must edit the Makefile -to add -DDEBUG to the compiler options.) - -For SunOS version 3.5, the popper program is launched by inetd from -/etc/servers. This file does not allow you to specify command line -arguments. Therefore, if you want to enable debugging, you can specify -a shell script in /etc/servers to be launched instead of popper and in -this script call popper with the desired arguments. - - -Installation - -1. Examine this file for the latest information, warnings, etc. - -2. Check the Makefile for conformity with your system. - -3. Issue the make command in the directory containing the popper - source. - -4. Issue the make install command in the directory containing the - popper source to copy the program to /usr/etc. - -5. Enable syslogging: - - + For systems with 4.3 syslogging: - - Add the following line to the /etc/syslog.conf file: - - local0.notice;local0.debug /usr/spool/mqueue/POPlog - - Create the empty file /usr/spool/mqueue/POPlog. - - Kill and restart the syslogd daemon. - - + For systems with 4.2 syslogging: - - Be sure that you are logging messages of priority 7 and higher. - For example: - - 7/usr/spool/mqueue/syslog - 9/dev/null - -6. Update /etc/services: - - Add the following line to the /etc/services file: - - pop 110/tcp - - Note: This is the official port number for version 3 of the - Post Office Protocol as defined in RFC 1081. However, some - POP3 clients use port 109, the port number for the previous - version (2) of POP. Therefore you may also want to add the - following line to the /etc/services file: - - pop2 109/tcp - - For Sun systems running yp, also do the following: - - + Change to the /var/yp directory. - - + Issue the make services command. - -7. Update the inetd daemon configuration. Include the second line ONLY if you - are running the server at both ports. - - + On BSD 4.3 and SunOS 4.0 systems, add the following line to the - /etc/inetd.conf file: - - pop stream tcp nowait root /usr/etc/popper popper - pop2 stream tcp nowait root /usr/etc/popper popper - - + On Ultrix systems, add the following line to the - /etc/inetd.conf file: - - pop stream tcp nowait /usr/etc/popper popper - pop2 stream tcp nowait /usr/etc/popper popper - - + On SunOS 3.5 systems, add the following line to the - /etc/servers file: - - pop tcp /usr/etc/popper - pop2 tcp /usr/etc/popper - - Kill and restart the inetd daemon. - -You can confirm that the POP server is running on Unix by telneting to -port 110 (or 109 if you set it up that way).

Unfortunately, if compiled with - -DDEBUG, this version could easily wipe out a users' mail file. - This is now fixed. - - This version also fixes a security hole for systems that have - /usr/spool/mail writeable by all users. - - With this version we go to all new SCCS IDs for all files. This - is unfortunate, and we hope it is not too much of a problem. - - Thanks to Steve Dorner of UIUC for pointing out the major problem. - -1.7 Extensive re-write of the maildrop processing code contributed by - Viktor Dukhovni <viktor@math.princeton.edu> that greatly reduces the - possibility that the maildrop can be corrupted as the result of - simultaneous access by two or more processes. - - Added "pop_dropcopy" module to create a temporary maildrop from - the existing, standard maildrop as root before the setuid and - setgid for the user is done. This allows the temporary maildrop - to be created in a mail spool area that is not world read-writable. - - This version does *not* send the sendmail "From " delimiter line - in response to a TOP or RETR command. - - Encased all debugging code in #ifdef DEBUG constructs. This code can - be included by specifying the DEGUG compiler flag. Note: You still - need to use the -d or -t option to obtain debugging output. - -1.6 Corrects a bug that causes the server to crash on SunOS - 4.0 systems. - - Uses varargs and vsprintf (if available) in pop_log and - pop_msg. This is enabled by the "HAVE_VSPRINTF" - compiler flag. - - For systems with BSD 4.3 bind, performs a cannonical - name lookup and searches the returned address(es) for - the client's address, logging a warning message if it - is not located. This is enabled by the "BIND43" - comiler flag. - - Removed all the includes from popper.h and distributed - them throughout the porgrams files, as needed. - - Reformatted the source to convert tabs to spaces and - shorten lines for display on 80-column terminals. - -1.5 Creates the temporary maildrop with mode "600" and - immediately unlinks it. - - Uses client's IP address in lieu of a canonical name if - the latter cannot be obtained. - - Added "-t <file-name>" option. The presence of this - option causes debugging output to be placed in the file - "file-name" using fprintf instead of the system log - file using syslog. - - Corrected maildrop parsing problem. - -1.4 Copies user's mail into a temporary maildrop on which - all subsequent activity is performed. - - Added "pop_log" function and replaced "syslog" calls - throughout the code with it. - -1.3 Corrected updating of Status: header line. - - Added strncasecmp for systems that do not have one. - Used strncasecmp in all appropriate places. This is - enabled by the STRNCASECMP compiler flag. - -1.2 Support for version 4.2 syslogging added. This is - enabled by the SYSLOG42 compiler flag. - -1.1 Several bugs fixed. - -1.0 Original version. - - -Limitations - -+ The POP server copies the user's entire maildrop to /tmp and - then operates on that copy. If the maildrop is particularly - large, or inadequate space is available in /tmp, then the - server will refuse to continue and terminate the connection. - -+ Simultaneous modification of a single maildrop can result in - confusing results. For example, manipulating messages in a - maildrop using the Unix /usr/ucb/mail command while a copy of - it is being processed by the POP server can cause the changes - made by one program to be lost when the other terminates. This - problem is being worked on and will be fixed in a later - release. - - -Credits - -The POP server was written by Edward Moy and Austin Shelton with -contributions from Robert Campbell (U.C.

Rose -Request for Comments: 1081 TWG - November 1988 - - Post Office Protocol - Version 3 - - -Status of this Memo - - This memo suggests a simple method for workstations to dynamically - access mail from a mailbox server. This RFC specifies a proposed - protocol for the Internet community, and requests discussion and - suggestions for improvements. Distribution of this memo is - unlimited. - - This memo is based on RFC 918 (since revised as RFC 937). Although - similar in form to the original Post Office Protocol (POP) proposed - for the Internet community, the protocol discussed in this memo is - similar in spirit to the ideas investigated by the MZnet project at - the University of California, Irvine. - - Further, substantial work was done on examining POP in a PC-based - environment. This work, which resulted in additional functionality - in this protocol, was performed by the ACIS Networking Systems Group - at Stanford University. The author gratefully acknowledges their - interest. - -Introduction - - On certain types of smaller nodes in the Internet it is often - impractical to maintain a message transport system (MTS). For - example, a workstation may not have sufficient resources (cycles, - disk space) in order to permit a SMTP server and associated local - mail delivery system to be kept resident and continuously running. - Similarly, it may be expensive (or impossible) to keep a personal - computer interconnected to an IP-style network for long amounts of - time (the node is lacking the resource known as "connectivity"). - - Despite this, it is often very useful to be able to manage mail on - these smaller nodes, and they often support a user agent (UA) to aid - the tasks of mail handling. To solve this problem, a node which can - support an MTS entity offers a maildrop service to these less endowed - nodes. The Post Office Protocol - Version 3 (POP3) is intended to - permit a workstation to dynamically access a maildrop on a server - host in a useful fashion. Usually, this means that the POP3 is used - to allow a workstation to retrieve mail that the server is holding - for it. - - - - -Rose [Page 1] - -RFC 1081 POP3 November 1988 - - - For the remainder of this memo, the term "client host" refers to a - host making use of the POP3 service, while the term "server host" - refers to a host which offers the POP3 service. - -A Short Digression - - This memo does not specify how a client host enters mail into the - transport system, although a method consistent with the philosophy of - this memo is presented here: - - When the user agent on a client host wishes to enter a message - into the transport system, it establishes an SMTP connection to - its relay host (this relay host could be, but need not be, the - POP3 server host for the client host). - - If this method is followed, then the client host appears to the MTS - as a user agent, and should NOT be regarded as a "trusted" MTS entity - in any sense whatsoever. This concept, along with the role of the - POP3 as a part of a split-UA model is discussed later in this memo. - - Initially, the server host starts the POP3 service by listening on - TCP port 110. When a client host wishes to make use of the service, - it establishes a TCP connection with the server host. When the - connection is established, the POP3 server sends a greeting. The - client and POP3 server then exchange commands and responses - (respectively) until the connection is closed or aborted. - - Commands in the POP3 consist of a keyword possibly followed by an - argument. All commands are terminated by a CRLF pair. - - Responses in the POP3 consist of a success indicator and a keyword - possibly followed by additional information. All responses are - terminated by a CRLF pair. There are currently two success - indicators: positive ("+OK") and negative ("-ERR"). - - Responses to certain commands are multi-line. In these cases, which - are clearly indicated below, after sending the first line of the - response and a CRLF, any additional lines are sent, each terminated - by a CRLF pair. When all lines of the response have been sent, a - final line is sent, consisting of a termination octet (decimal code - 046, ".") and a CRLF pair. If any line of the multi-line response - begins with the termination octet, the line is "byte-stuffed" by - pre-pending the termination octet to that line of the response. - Hence a multi-line response is terminated with the five octets - "CRLF.CRLF". When examining a multi-line response, the client checks - to see if the line begins with the termination octet. If so and if - octets other than CRLF follow, the the first octet of the line (the - termination octet) is stripped away. If so and if CRLF immediately - - - -Rose [Page 2] - -RFC 1081 POP3 November 1988 - - - follows the termination character, then the response from the POP - server is ended and the line containing ".CRLF" is not considered - part of the multi-line response. - - A POP3 session progresses through a number of states during its - lifetime. Once the TCP connection has been opened and the POP3 - server has sent the greeting, the session enters the AUTHORIZATION - state. In this state, the client must identify itself to the POP3 - server. Once the client has successfully done this, the server - acquires resources associated with the client's maildrop, and the - session enters the TRANSACTION state. In this state, the client - requests actions on the part of the POP3 server. When the client has - finished its transactions, the session enters the UPDATE state. In - this state, the POP3 server releases any resources acquired during - the TRANSACTION state and says goodbye. The TCP connection is then - closed. - -The AUTHORIZATION State - - Once the TCP connection has been opened by a POP3 client, the POP3 - server issues a one line greeting. This can be any string terminated - by CRLF. An example might be: - - S. +OK dewey POP3 server ready (Comments to: PostMaster@UDEL.EDU) - - Note that this greeting is a POP3 reply. The POP3 server should - always give a positive response as the greeting. - - The POP3 session is now in the AUTHORIZATION state. The client must - now issue the USER command. If the POP3 server responds with a - positive success indicator ("+OK"), then the client may issue either - the PASS command to complete the authorization, or the QUIT command - to terminate the POP3 session. If the POP3 server responds with a - negative success indicator ("-ERR") to the USER command, then the - client may either issue a new USER command or may issue the QUIT - command. - - When the client issues the PASS command, the POP3 server uses the - argument pair from the USER and PASS commands to determine if the - client should be given access to the appropriate maildrop. If so, - the POP3 server then acquires an exclusive-access lock on the - maildrop. If the lock is successfully acquired, the POP3 server - parses the maildrop into individual messages (read note below), - determines the last message (if any) present in the maildrop that was - referenced by the RETR command, and responds with a positive success - indicator. The POP3 session now enters the TRANSACTION state. If - the lock can not be acquired or the client should is denied access to - the appropriate maildrop or the maildrop can't be parsed for some - - - -Rose [Page 3] - -RFC 1081 POP3 November 1988 - - - reason, the POP3 server responds with a negative success indicator. - (If a lock was acquired but the POP3 server intends to respond with a - negative success indicator, the POP3 server must release the lock - prior to rejecting the command.) At this point, the client may - either issue a new USER command and start again, or the client may - issue the QUIT command. - - NOTE: Minimal implementations of the POP3 need only be - able to break a maildrop into its component messages; - they need NOT be able to parse individual messages. - More advanced implementations may wish to have this - capability, for reasons discussed later. - - After the POP3 server has parsed the maildrop into individual - messages, it assigns a message-id to each message, and notes the size - of the message in octets. The first message in the maildrop is - assigned a message-id of "1", the second is assigned "2", and so on, - so that the n'th message in a maildrop is assigned a message-id of - "n". In POP3 commands and responses, all message-id's and message - sizes are expressed in base-10 (i.e., decimal). - - It sets the "highest number accessed" to be that of the last message - referenced by the RETR command. - - Here are summaries for the three POP3 commands discussed thus far: - - USER name - Arguments: a server specific user-id (required) - Restrictions: may only be given in the AUTHORIZATION - state after the POP3 greeting or after an - unsuccessful USER or PASS command - Possible Responses: - +OK name is welcome here - -ERR never heard of name - Examples: - C: USER mrose - S: +OK mrose is a real hoopy frood - ... - C: USER frated - S: -ERR sorry, frated doesn't get his mail here - - PASS string - Arguments: a server/user-id specific password (required) - Restrictions: may only be given in the AUTHORIZATION - state after a successful USER command - Possible Responses: - +OK maildrop locked and ready - -ERR invalid password - - - -Rose [Page 4] - -RFC 1081 POP3 November 1988 - - - -ERR unable to lock maildrop - Examples: - C: USER mrose - S: +OK mrose is a real hoopy frood - C: PASS secret - S: +OK mrose's maildrop has 2 messages - (320 octets) - ... - C: USER mrose - S: +OK mrose is a real hoopy frood - C: PASS secret - S: -ERR unable to lock mrose's maildrop, file - already locked - - QUIT - Arguments: none - Restrictions: none - Possible Responses: - +OK - Examples: - C: QUIT - S: +OK dewey POP3 server signing off - - -The TRANSACTION State - - Once the client has successfully identified itself to the POP3 server - and the POP3 server has locked and burst the appropriate maildrop, - the POP3 session is now in the TRANSACTION state.

In - order for this command to be successful, the POP3 - client must use a reserved TCP port (port < 1024) to - connect tothe server. The POP3 server uses the - argument pair from the USER and RPOP commands to - determine if the client should be given access to - the appropriate maildrop. Unlike the PASS command - however, the POP3 server considers if the remote user - specified by the RPOP command who resides on the POP3 - client host is allowed to access the maildrop for the - user specified by the USER command (e.g., on Berkeley - UNIX, the .rhosts mechanism is used).

Usually, - during the AUTHORIZATION state of the POP3 session, the POP3 client - can calculate the size of each message in octets when it parses the - maildrop into messages. For example, if the POP3 server host - internally represents end-of-line as a single character, then the - POP3 server simply counts each occurrence of this character in a - message as two octets. Note that lines in the message which start - with the termination octet need not be counted twice, since the POP3 - client will remove all byte-stuffed termination characters when it - receives a multi-line response. - -The POP and the Split-UA model - - The underlying paradigm in which the POP3 functions is that of a - split-UA model. The POP3 client host, being a remote PC based - workstation, acts solely as a client to the message transport system. - It does not provide delivery/authentication services to others. - Hence, it is acting as a UA, on behalf of the person using the - workstation. Furthermore, the workstation uses SMTP to enter mail - into the MTS. - - In this sense, we have two UA functions which interface to the - message transport system: Posting (SMTP) and Retrieval (POP3). The - entity which supports this type of environment is called a split-UA - (since the user agent is split between two hosts which must - interoperate to provide these functions). - - ASIDE: Others might term this a remote-UA instead. - There are arguments supporting the use of both terms. - - This memo has explicitly referenced TCP as the underlying transport - agent for the POP3. This need not be the case. In the MZnet split- - UA, for example, personal micro-computer systems are used which do - not have IP-style networking capability. To connect to the POP3 - server host, a PC establishes a terminal connection using some simple - protocol (PhoneNet). A program on the PC drives the connection, - first establishing a login session as a normal user. The login shell - - - -Rose [Page 14] - -RFC 1081 POP3 November 1988 - - - for this pseudo-user is a program which drives the other half of the - terminal protocol and communicates with one of two servers. Although - MZnet can support several PCs, a single pseudo-user login is present - on the server host. The user-id and password for this pseudo-user - login is known to all members of MZnet. Hence, the first action of - the login shell, after starting the terminal protocol, is to demand a - USER/PASS authorization pair from the PC. This second level of - authorization is used to ascertain who is interacting with the MTS. - Although the server host is deemed to support a "trusted" MTS entity, - PCs in MZnet are not. Naturally, the USER/PASS authorization pair - for a PC is known only to the owner of the PC (in theory, at least). - - After successfully verifying the identity of the client, a modified - SMTP server is started, and the PC posts mail with the server host. - After the QUIT command is given to the SMTP server and it terminates, - a modified POP3 server is started, and the PC retrieves mail from the - server host. After the QUIT command is given to the POP3 server and - it terminates, the login shell for the pseudo-user terminates the - terminal protocol and logs the job out. The PC then closes the - terminal connection to the server host. - - The SMTP server used by MZnet is modified in the sense that it knows - that it's talking to a user agent and not a "trusted" entity in the - message transport system. Hence, it does performs the validation - activities normally performed by an entity in the MTS when it accepts - a message from a UA. - - The POP3 server used by MZnet is modified in the sense that it does - not require a USER/PASS combination before entering the TRANSACTION - state. The reason for this (of course) is that the PC has already - identified itself during the second-level authorization step - described above. - - NOTE: Truth in advertising laws require that the author - of this memo state that MZnet has not actually been - fully implemented. The concepts presented and proven - by the project led to the notion of the MZnet - split-slot model. This notion has inspired the - split-UA concept described in this memo, led to the - author's interest in the POP, and heavily influenced - the the description of the POP3 herein. - - In fact, some UAs present in the Internet already support the notion - of posting directly to an SMTP server and retrieving mail directly - from a POP server, even if the POP server and client resided on the - same host! - - ASIDE: this discussion raises an issue which this memo - - - -Rose [Page 15] - -RFC 1081 POP3 November 1988 - - - purposedly avoids: how does SMTP know that it's talking - to a "trusted" MTS entity? - -References - - [MZnet] Stefferud, E., J.

All of the - extensions described in this memo to the POP3 are OPTIONAL. - Distribution of this memo is unlimited. - -Introduction and Motivation - - It is assumed that the reader is familiar with RFC 1081 that - discusses the Post Office Protocol - Version 3 (POP3) [RFC1081]. - This memo describes extensions to the POP3 which enhance the service - it offers to clients. This additional service permits a client host - to access discussion group mail, which is often kept in a separate - spool area, using the general POP3 facilities. - - The next section describes the evolution of discussion groups and the - technologies currently used to implement them. To summarize: - - o An exploder is used to map from a single address to - a list of addresses which subscribe to the list, and redirects - any subsequent error reports associated with the delivery of - each message. This has two primary advantages: - - Subscribers need know only a single address - - Responsible parties get the error reports and not - the subscribers - - - - - - - - - - - - -Rose [Page 1] - -RFC 1082 POP3 Extended Service November 1988 - - - o Typically, each subscription address is not a person's private - maildrop, but a system-wide maildrop, which can be accessed - by more than one user. This has several advantages: - - Only a single copy of each message need traverse the - net for a given site (which may contain several local - hosts). This conserves bandwidth and cycles. - - Only a single copy of each message need reside on each - subscribing host. This conserves disk space. - - The private maildrop for each user is not cluttered - with discussion group mail. - - Despite this optimization of resources, further economy can be - achieved at sites with more than one host. Typically, sites with - more than one host either: - - 1. Replicate discussion group mail on each host. This - results in literally gigabytes of disk space committed to - unnecessarily store redundant information. - - 2. Keep discussion group mail on one host and give all users a - login on that host (in addition to any other logins they may - have). This is usually a gross inconvenience for users who - work on other hosts, or a burden to users who are forced to - work on that host. - - As discussed in [RFC1081], the problem of giving workstations dynamic - access to mail from a mailbox server has been explored in great - detail (originally there was [RFC918], this prompted the author to - write [RFC1081], independently of this [RFC918] was upgraded to - [RFC937]). A natural solution to the problem outlined above is to - keep discussion group mail on a mailbox server at each site and - permit different hosts at that site to employ the POP3 to access - discussion group mail. If implemented properly, this avoids the - problems of both strategies outlined above. - - ASIDE: It might be noted that a good distributed filesystem - could also solve this problem. Sadly, "good" - distributed filesystems, which do not suffer - unacceptable response time for interactive use, are - few and far between these days! - - Given this motivation, now let's consider discussion groups, both in - general and from the point of view of a user agent. Following this, - extensions to the POP3 defined in [RFC1081] are presented. Finally, - some additional policy details are discussed along with some initial - experiences. - - - - - -Rose [Page 2] - -RFC 1082 POP3 Extended Service November 1988 - - -What's in a Discussion Group - - Since mailers and user agents first crawled out of the primordial - ARPAnet, the value of discussion groups have been appreciated, - (though their implementation has not always been well-understood). - - Described simply, a discussion group is composed of a number of - subscribers with a common interest. These subscribers post mail to a - single address, known as a distribution address. From this - distribution address, a copy of the message is sent to each - subscriber. Each group has a moderator, which is the person that - administrates the group. The moderator can usually be reached at a - special address, known as a request address. Usually, the - responsibilities of the moderator are quite simple, since the mail - system handles the distribution to subscribers automatically. In - some cases, the interest group, instead of being distributed directly - to its subscribers, is put into a digest format by the moderator and - then sent to the subscribers. Although this requires more work on - the part of the moderator, such groups tend to be better organized. - - Unfortunately, there are a few problems with the scheme outlined - above. First, if two users on the same host subscribe to the same - interest group, two copies of the message get delivered. This is - wasteful of both processor and disk resources. - - Second, some of these groups carry a lot of traffic. Although - subscription to an group does indicate interest on the part of a - subscriber, it is usually not interesting to get 50 messages or so - delivered to the user's private maildrop each day, interspersed with - personal mail, that is likely to be of a much more important and - timely nature. - - Third, if a subscriber on the distribution list for a group becomes - "bad" somehow, the originator of the message and not the moderator of - the group is notified. It is not uncommon for a large list to have - 10 or so bogus addresses present. This results in the originator - being flooded with "error messages" from mailers across the Internet - stating that a given address on the list was bad. Needless to say, - the originator usually could not care less if the bogus addresses got - a copy of the message or not. The originator is merely interested in - posting a message to the group at large. Furthermore, the moderator - of the group does care if there are bogus addresses on the list, but - ironically does not receive notification. - - There are various approaches which can be used to solve some or all - of these problems. Usually these involve placing an exploder agent - at the distribution source of the discussion group, which expands the - name of the group into the list of subscription addresses for the - - - -Rose [Page 3] - -RFC 1082 POP3 Extended Service November 1988 - - - group. In the process, the exploder will also change the address - that receives error notifications to be the request address or other - responsible party. - - A complementary approach, used in order to cut down on resource - utilization of all kinds, replaces all the subscribers at a single - host (or group of hosts under a single administration) with a single - address at that host. This address maps to a file on the host, - usually in a spool area, which all users can access. (Advanced - implementations can also implement private discussion groups this - way, in which a single copy of each message is kept, but is - accessible to only a select number of users on the host.) - - The two approaches can be combined to avoid all of the problems - described above. - - Finally, a third approach can be taken, which can be used to aid user - agents processing mail for the discussion group: In order to speed - querying of the maildrop which contains the local host's copy of the - discussion group, two other items are usually associated with the - discussion group, on a local basis. These are the maxima and the - last-date. Each time a message is received for the group on the - local host, the maxima is increased by at least one. Furthermore, - when a new maxima is generated, the current date is determined. This - is called the last date. As the message is entered into the local - maildrop, it is given the current maxima and last-date. This permits - the user agent to quickly determine if new messages are present in - the maildrop. - - NOTE: The maxima may be characterized as a monotonically - increasing quanity. Although sucessive values of the - maxima need not be consecutive, any maxima assigned - is always greater than any previously assigned value. - -Definition of Terms - - To formalize these notions somewhat, consider the following 7 - parameters which describe a given discussion group from the - perspective of the user agent (the syntax given is from [RFC822]): - - - - - - - - - - - - -Rose [Page 4] - -RFC 1082 POP3 Extended Service November 1988 - - - NAME Meaning: the name of the discussion group - Syntax: TOKEN (ALPHA *[ ALPHA / DIGIT / "-" ]) - (case-insensitive recognition) - Example: unix-wizards - - ALIASES Meaning: alternates names for the group, which - are locally meaningful; these are - typically used to shorten user typein - Syntax: TOKEN (case-insensitive recognition) - Example: uwiz - - ADDRESS Meaning: the primary source of the group - Syntax: 822 address - Example: Unix-Wizards@BRL.MIL - - REQUEST Meaning: the primary moderator of the group - Syntax: 822 address - Example: Unix-Wizards-Request@BRL.MIL - - FLAGS Meaning: locally meaningful flags associated - with the discussion group; this memo - leaves interpretation of this - parameter to each POP3 implementation - Syntax: octal number - Example: 01 - - MAXIMA Meaning: the magic cookie associated with the - last message locally received for the - group; it is the property of the magic - cookie that it's value NEVER - decreases, and increases by at least - one each time a message is locally - received - Syntax: decimal number - Example: 1004 - - LASTDATE Meaning: the date that the last message was - locally received - Syntax: 822 date - Example: Thu, 19 Dec 85 10:26:48 -0800 - - Note that the last two values are locally determined for the maildrop - associated with the discussion group and with each message in that - maildrop.

This often - occurs when the maildrop has been archived. - - - - - -Rose [Page 5] - -RFC 1082 POP3 Extended Service November 1988 - - - Finally, some local systems provide mechanisms for automatically - archiving discussion group mail. In some cases, a two-level archive - scheme is used: current mail is kept in the standard maildrop, - recent mail is kept in an archive maildrop, and older mail is kept - off-line. With this scheme, in addition to having a "standard" - maildrop for each discussion group, an "archive" maildrop may also be - available. This permits a user agent to examine the most recent - archive using the same mechanisms as those used on the current mail. - -The XTND Command - - The following commands are valid only in the TRANSACTION state of the - POP3. This implies that the POP3 server has already opened the - user's maildrop (which may be empty). This maildrop is called the - "default maildrop". The phrase "closes the current maildrop" has two - meanings, depending on whether the current maildrop is the default - maildrop or is a maildrop associated with a discussion group. - - In the former context, when the current maildrop is closed any - messages marked as deleted are removed from the maildrop currently in - use. The exclusive-access lock on the maildrop is then released - along with any implementation-specific resources (e.g., file- - descriptors). - - In the latter context, a maildrop associated with a discussion group - is considered to be read-only to the POP3 client. In this case, the - phrase "closes the current maildrop" merely means that any - implementation-specific resources are released. (Hence, the POP3 - command DELE is a no-op.) - - All the new facilities are introduced via a single POP3 command, - XTND. All positive reponses to the XTND command are multi-line. - - The most common multi-line response to the commands contains a - "discussion group listing" which presents the name of the discussion - group along with it's maxima. In order to simplify parsing all POP3 - servers are required to use a certain format for discussion group - listings: - - NAME SP MAXIMA - - This memo makes no requirement on what follows the maxima in the - listing.

Private Discussion Groups - - In the general case, discussion groups are world-readable, any user, - once logged in (via a terminal, terminal server, or POP3, etc.), is - able to read the maildrop for each discussion group known to the POP3 - service host. Nevertheless, it is desirable, usually for privacy - reasons, to implement private discussion groups as well. - - Support of this is consistent with the extensions outlined in this - - - -Rose [Page 9] - -RFC 1082 POP3 Extended Service November 1988 - - - memo. Once the AUTHORIZATION state has successfully concluded, the - POP3 server grants the user access to exactly those discussion groups - the POP3 service host permits the authenticated user to access. As a - "security" feature, discussion groups associated with unreadable - maildrops should not be listed in a positive response to the XTND - BBOARDS command. - - 2. Anonymous POP3 Users - - In order to minimize the authentication problem, a policy permitting - "anonymous" access to the world-readable maildrops for discussion - groups on the POP3 server may be implemented. - - Support of this is consistent with the extensions outlined in this - memo. The POP3 server can be modified to accept a USER command for a - well-known pseudonym (i.e., "anonymous") which is valid with any PASS - command. As a "security" feature, it is advisable to limit this kind - of access to only hosts at the local site, or to hosts named in an - access list. - -Experiences and Conclusions - - All of the facilities described in this memo and in [RFC1081] have - been implemented in MH #6.1. Initial experiences have been, on the - whole, very positive. - - After the first implementation, some performance tuning was required. - This consisted primarily of caching the datastructures which describe - discussion groups in the POP3 server. A second optimization - pertained to the client: the program most commonly used to read - BBoards in MH was modified to retrieve messages only when needed. - Two schemes are used: - - o If only the headers (and the first few lines of the body) of - the message are required (e.g., for a scan listing), then only - these are retrieved. The resulting output is then cached, on - a per-message basis. - - o If the entire message is required, then it is retrieved intact, - and cached locally. - - With these optimizations, response time is quite adequate when the - POP3 server and client are connected via a high-speed local area - network. In fact, the author uses this mechanism to access certain - private discussion groups over the Internet. In this case, response - is still good. When a 9.6Kbps modem is inserted in the path, - response went from good to almost tolerable (fortunately the author - only reads a few discussion groups in this fashion). - - - -Rose [Page 10] - -RFC 1082 POP3 Extended Service November 1988 - - - To conclude: the POP3 is a good thing, not only for personal mail but - for discussion group mail as well. - - -References - - [RFC1081] Rose, M., "Post Office Protocol - Verison 3 (POP3)", RFC - 1081, TWG, November 1988. - - [MRose85] Rose, M., and J.

The server was developed at the University of -California at Berkeley and conforms fully to the specifications in RFC -1081 and RFC 1082. The Berkeley server also has extensions to send -electronic mail on behalf of a client. -.PP -The -.B \-d -flag sets the socket to debugging and turns on debugging. All debugging -information is saved using syslog(8). The -.B \-t trace\-file -flag turns on debugging and saves the trace information in -.I trace\-file -using fprintf(s). -.SH HOW TO OBTAIN THE SERVER -.PP -The POP server is available via anonymous ftp from ftp.CC.Berkeley.EDU -(128.32.136.9, 128.32.206.12). It is in two files in the pub directory: -a compressed tar file popper.tar.Z and a Macintosh StuffIt archive in -BinHex format called MacPOP.sit.hqx. -.SH THE POP TRANSACTION CYCLE -.PP -The Berkeley POP server is a single program (called popper) that is -launched by inetd when it gets a service request on the POP TCP port. -(The official port number specified in RFC 1081 for POP version 3 is -port 110. However, some POP3 clients attempt to contact the server at -port 109, the POP version 2 port. Unless you are running both POP2 and -POP3 servers, you can simply define both ports for use by the POP3 -server. This is explained in the installation instructions later on.) -The popper program initializes and verifies that the peer IP address is -registered in the local domain, logging a warning message when a -connection is made to a client whose IP address does not have a -canonical name. For systems using BSD 4.3 bind, it also checks to see -if a cannonical name lookup for the client returns the same peer IP -address, logging a warning message if it does not. The the server -enters the authorization state, during which the client must correctly -identify itself by providing a valid Unix userid and password on the -server's host machine. No other exchanges are allowed during this state -(other than a request to quit.) If authentication fails, a warning -message is logged and the session ends. Once the user is identified, -popper changes its user and group ids to match that of the user and -enters the transaction state. The server makes a temporary copy of the -user's maildrop (ordinarily in /usr/spool/mail) which is used for all -subsequent transactions. These include the bulk of POP commands to -retrieve mail, delete mail, undelete mail, and so forth. A Berkeley -extension also allows the user to submit a mail parcel to the server who -mails it using the sendmail program (this extension is supported in the -HyperMail client distributed with the server). When the client quits, -the server enters the final update state during which the network -connection is terminated and the user's maildrop is updated with the -(possibly) modified temporary maildrop. -.SH LOGGING -.PP -The POP server uses syslog to keep a record of its activities. On -systems with BSD 4.3 syslogging, the server logs (by default) to the -"local0" facility at priority "notice" for all messages except debugging -which is logged at priority "debug". The default log file is -/usr/spool/mqueue/POPlog. These can be changed, if desired. On systems -with 4.2 syslogging all messages are logged to the local log file, -usually /usr/spool/mqueue/syslog. -.SH DEBUGGING -.PP -The popper program will log debugging information when the -d parameter -is specified after its invocation in the inetd.conf file. Care should -be exercised in using this option since it generates considerable output -in the syslog file. Alternatively, the "-t <file-name>" option will -place debugging information into file "<file-name>" using fprintf -instead of syslog. -.PP -For SunOS version 3.5, the popper program is launched by inetd from -/etc/servers. This file does not allow you to specify command line -arguments. Therefore, if you want to enable debugging, you can specify -a shell script in /etc/servers to be launched instead of popper and in -this script call popper with the desired arguments. -.PP -You can confirm that the POP server is running on Unix by telneting to -port 110 (or 109 if you set it up that way). For example: -.PP -.nf -%telnet myhost 110 -Trying... -Connected to myhost.berkeley.edu. -Escape character is '^]'. -+OK UCB Pop server (version 1.6) at myhost starting. -quit -Connection closed by foreign host. -.fi -.SH VERSION 1.7 RELEASE NOTES -Extensive re-write of the maildrop processing code contributed by Viktor -Dukhovni <viktor@math.princeton.edu> that greatly reduces the -possibility that the maildrop can be corrupted as the result of -simultaneous access by two or more processes. -.PP -Added "pop_dropcopy" module to create a temporary maildrop from the -existing, standard maildrop as root before the setuid and setgid for the -user is done. This allows the temporary maildrop to be created in a -mail spool area that is not world read-writable. -.PP -This version does *not* send the sendmail "From " delimiter line in -response to a TOP or RETR command. -.PP -Encased all debugging code in #ifdef DEBUG constructs. This code can be -included by specifying the DEGUG compiler flag. Note: You still need -to use the -d or -t option to obtain debugging output. -.SH LIMITATIONS -The POP server copies the user's entire maildrop to /tmp and then -operates on that copy. If the maildrop is particularly large, or -inadequate space is available in /tmp, then the server will refuse to -continue and terminate the connection. -.PP -Simultaneous modification of a single maildrop can result in confusing -results. For example, manipulating messages in a maildrop using the -Unix /usr/ucb/mail command while a copy of it is being processed by the -POP server can cause the changes made by one program to be lost when the -other terminates. This problem is being worked on and will be fixed in -a later release. -.SH FILES -.nf -/usr/spool/mail mail files -/etc/inetd.conf pop program invocation -/etc/syslog.conf logging specifications -.fi -.SH "SEE ALSO" -inetd(8), -RFC1081, -RFC1082 -.SH AUTHORS -Bob Campbell, Edward Moy, Austin Shelton, Marshall T Rose, and cast of -thousands at Rand, UDel, UCI, and elsewhere diff --git a/src/appl/popper/popper.c b/src/appl/popper/popper.c deleted file mode 100644 index 2c980f3..0000000 --- a/src/appl/popper/popper.c +++ /dev/null @@ -1,113 +0,0 @@ -/* - * Copyright (c) 1989 Regents of the University of California. - * All rights reserved.
