Then desktop computer users can use "terminal sessions" to + sign on to the central mail server and read their mail (e.g. with Unix + "pine"). This has the disadvantage of making the desktop computer + users learn and use the central mail server's procedures. + + SMTP, the "internet" mail protocol used to deliver mail between + multi-user systems only supports mail transfer initiated by the sender + to actually, it has a method to initiate reception, but the method + didn't catch on and is not used). Other protocols have been devised to + allow a desktop computer to request transfer of mail, thus able to + make use of a central server. These include the published variants of + POP, IMAP, and DMSP. + + POP, POP2, POP3 + + + + These are rather minimal and are designed to be so. The three are + similar but not enough alike to be interoperable. They are basically + designed to identify the user by username and password, to transfer + the mail from server to desktop computer and to delete the mail + transferred. It is assumed that SMTP will be used to send mail. + Messages can be retrieved individually, but the only information you + can get about a message without transferring it is its length in + bytes-- useful for desktop computers with limited storage. + + POP3 has a number of optional extensions including Xtnd Xmit which + allows clients to send mail through the POP3 session rather than using + SMTP. Another extension is APOP which allows RSA MD5 encryption of + passwords passed over the network. + + POP3 is now by far the most-used variant of POP, but POP2 may still be + used at a few sites. POP3 has a couple of optional extensions: one to + avoid sending passwords, and one to aid in reading bulletin boards. + + IMAP2, IMAP2BIS, IMAP3, IMAP4, IMAP4REV1 + + + + The IMAP family is similar to the POP family, but also gives clients a + way to do string searches through mail that still resides on the + server. This is designed to allow the desktop computer to be more + selective as to which mail will be transferred. The POP protocols, on + the other hand, are designed for simpler server software. + + IMAP2 is used quite a bit. IMAP3 is an incompatible offshoot that has + not been implemented much. IMAP4 is a relatively recent extension of + IMAP2 which makes the servers cognizant of the MIME-structure of a + message. IMAP2bis was the original name of IMAP4, which has since been + refined, but there are/were some implementations of IMAP2bis that are + not IMAP4 compliant. IMAP4 also extends IMAP to have many other + features including some of DMSP's. IMAP4rev1 includes a few + enhancements to IMAP4. + + ACAP + + + + ACAP (Application Configuration Access Protocol), formerly IMSP + (Interactive Mail Support Protocol), is a protocol which is being + developed to compliment IMAP4 by offering related e-mail services + beyond the scope of IMAP4. It includes the ability to subscribe find & + subscribe to bulletin boards, mailboxes, and to find and search + address books. + + IMAP VS POP + + + + As of this writing (10/96), there are a many more POP than IMAP client + implementations and an Internet Service Provider is much more likely + to provide POP3 service than IMAP4. But interest in IMAP4 is growing + with big-time software houses announcing support. IMAP4 has more + features, basically designed to support a model where users store + their received mail on a server rather than on their own computer. The + big advantage cited for IMAP is that people who "do e-mail" from + different computers at different times have the same access to their + message store from any of the client-computers they use. The cost of + this model (aside from issues such as the complexity and the + availability of implementations) is in running a server with + sufficient space for the clients' message stores. With personal + computer disks now often above a gigabyte (presumeably growing to 10s + of gigabytes over the next few years) and multimedia messaging in our + future, people storing e-mail on their own hard disk will have a lot + of space and ways to use it. A central store serving 10-20 users will + not be overly difficult, but one for 1,000 or 10,000 users will be + very large (terabytes?) if it is to offer comparable space. The + question comes down to the tradeoff between the advantage to users who + computer-hop against the costs of managing the large amount of central + store. See also online document imap.vs.pop.html (reference below) and + section below "Issue of Remote Access". + + DMSP + + + + Also know as PCMAIL. Desktop computers can use this protocol to both + send and receive mail. The system is designed around the idea that + each user can own more than one workstation; however, the system + doesn't seem to handle the idea of a "public workstation" very well. + The desktop computers are assumed to hold state information about the + mail, a directory so to speak, and when the desktop computer is + connected to the server, this directory is updated to "reality". Note: + DMSP never gained the following of IMAP or POP and I've heard the + software is no longer available. + + WHO USES THESE PROTOCOLS? + + + + These protocols were designed and implemented mostly by + Internet-connected universities with some participation by other + Internet-connected research institutions. They were certainly devised + to handle the type of electronic mail that universities must do. A + typical site has probably 10 to 10,000 desktop computers and has an + Internet connection and also runs Unix, giving them the Unix sysadmin + expertise that makes running a Unix-based server attractive. Most of + the servers listed here run under Unix though some run under other + large systems and as time goes on, we are seeing more servers that run + on PCs and Macintoshes. + + A more recent use of these protocols has been by Internet Service + Providers and their customers. Internet Service Providers require a + way to offer e-mail services to however many customers they provide, + to customers who are connected to the network only part of the time. + Like a campus application, they may have 10 or 10,000 customers to + serve. These protocols offer a distinct advantage over SMTP for such + purposes and form an attractive complementary e-mail service for WWW + users. + + DISADVANTAGES + + + + There are a number of disadvantages associated with the use of these + protocols: + * since these have long been no more than a small part of the e-mail + market, software using these methods is often incompatible with + other useful and/or well-known software. A couple of examples are: + + Use of mail-enabled applications on desktop computers (there + is no fundamental reason that mail software using these + protocols can't provide the API used by mail-enabled + applications, but in general this hasn't come about yet) + + Use of the usual Unix mail readers & the Unix .forward files. + * since the server is holding mail for the person, the person can + use the server for storage. This leaves the potential for all the + disk-space problems inherent in shared disks: people hogging + disk-space or forgetting to clean up, etc. + * sizing the server: a perennial question people ask is "How big a + machine do I need to serve my campus (or department, or + whatever)". Naturally no one can give a straight answer because it + depends upon so many factors. + + ISSUE OF REMOTE ACCESS + + + + Modern commercial e-mail packages typically have features designed to + assist in remote access of ones e-mail. Features include: + * ability to download mail through a modem + * ability to synchronize two different systems which you are using + to read your e-mail by plugging them together. + + + + Any method of reading e-mail using PCs or Macintoshes can be used + remotely via remote control (the "PCanywhere(tm)" method, e.g. by + dialing up your own office PC/Macintosh and using one of the several + kinds of software that allow you to control your PC/Macintosh over the + phone). Also, any LAN-based method can be used by using one of the + several methods of providing the same protocol support over dialup + lines as are on LANs (SLIP or PPP for the above-mentioned, + TCP/IP-based protocols, ARA for Appletalk-based protocols, etc, and + sometimes using two different protocols, one incapsulated in the + other) under the constraint that any operations that use the network + will be much slower. Also, POP3 is sometime used directly over modems + (for example, Eudora can be used in this manner). + + The ideal protocol for remote access would not penalize the user for + the much slower communications speed (usually slower by a factor of + 100: note that a lot of LAN-based software was written without regard + to minimizing the necessary communication, thus is really hurt by such + slow speeds), yet would allow the same software to run both remotely + and locally, with a wonderful user interface. It would also not be + overly expensive in communications equipment or services. This is a + difficult set of objectives and the above-three protocols can achieve + some of them for some users, but what they actually achieve depends a + lot on the user's pattern of e-mail usage. If a user reads just a + small amount of mail, then we would not worry about the length of time + necessary to download it remotely with POP3, but if the person + receives a lot of mail, but just wants to read a small amount of it at + home, then with IMAP2, they could pick and choose what to read, + eliminating some download time. If someone is paying for the telephone + line time (possibly the user if it is a long distance call; in any + case, the institution pays a monthly fee for each line it offers, + which is dependent upon how many users it is serving, how often they + call, and how long their calls are) then IMAP2's natural method of + usage which requires the phone call to remain while a user is reading, + poking around, sending, and rearranging mail can be much more costly + than using POP3 if one call is used to quickly download all the mail + and another later call is used to send any replies. Thus with POP3 a + user might have two 1 minute calls before and after a 30 minute e-mail + session instead of keeping the call for 30 minutes with IMAP2, and + each phone line the institution offers could be serving 15 times as + many such users who would each pay a lot less in long-distance phone + bills. Note that with the advent of multimedia mail (see MIME below) + whose messages can be very large, it is possible that downloading even + one message that you end up not reading remotely could ruin such a + nice-sounding scenario. + + Note that with the growth of Internet Service Providers, remote access + is becoming the normal way for many people to do their e-mail, and + offering such services is one of the major growth areas for POP and + IMAP. + + MIME + + + + MIME (Multipurpose Internet Mail Extensions) is a relatively new + Internet standard for the format for messages with multiple parts, and + with non-ASCII data. Any client that can import or export files can + use MIME in a clumsy way if you have a program to create and/or decode + a MIME message. Some clients have built-in features to do this. + Client-server mail protocols generally only deal with entire messages, + and can retrieve MIME messages as well as any other messages since + MIME was carefully designed to be transparent to existing mail + systems. However, IMAP4 has features to allow retrieval of individual + parts of MIME-encoded messages. The chart below lists whether a + package has MIME support. Servers for protocols that don't offer any + special MIME features are marked na for Not Applicable since they need + do nothing for users to use MIME. All IMAP4 servers can also do this, + but the chart lists whether they include explicit MIME support. + + APPROACHES NOT COVERED BY THIS MEMO + * Proprietary protocols + * file sharing + * APIs + * X.400. + + + + Vendors can invent their own protocols similar to those listed above, + and some have. + + LAN e-mail can also be implemented using file sharing, e.g. using NFS + to allow separate Unix workstations to share the same mail spool area + just as if it were mail being stored on one system, or using Novell's + SMF (Simple Message Format) in a Novell file server. If the + applications are written so that they are careful to lock files + correctly, then this works. An advantage is that any network file + protocol can be used and the e-mail application can be somewhat + independent of the file protocol. For example, Unix systems could use + either AFS or NFS. Pegasus is a PC & Mac application that uses Novell + file service to do something similar. Specifications for client-server + interaction consist of the file service protocol along with the server + directory structures & conventions used for storing e-mail. + + A very popular approach with commercial vendors is the use of APIs. + The client talks to the server using an API (Applications Programming + Interface), i.e., a set of subroutine/procedure library call + definitions for a library providing subroutines/procedures to send, + receive, and manipulate e-mail. With the use of any remote procedure + call mechanism, the client can be located on a different computer from + the server. This allows some mixing and matching of RPC mechanisms, + underlying protocol stacks and APIs: e.g., a vendor defines an API, + and it can be run over IPX or TCP/IP, in each case over the protocol + stack's RPC mechanism. There are a number of APIs now being pushed by + vendors: MAPI (Microsoft); VIM (Lotus); AOCE (Apple). These API's have + been the basis for numerous mail-enabled applications: e.g. a word + processor that allows you to send or receive documents through e-mail + simply uses one of these APIs allowing it to communicate with any + server supporting the same API. Specifications for client-server + interaction consist of the protocol stack up to the RPC protocol, then + the API itself. + + Note that though the API approach in combination with remote procedure + calls allows one to implement client-server e-mail without the use of + the protocols covered by this document (IMAP, POP, etc), that there is + no theoretical reason why such APIs can't be used in an IMAP or POP + environment. The necessary software would be a "driver" or piece of + "middleware" that provides the APIs calls to mail-enabled applications + and uses POP, IMAP, or whatever over a LAN to reach a server. The + advantages/disadvantages of such an approach as compared to the use of + RPCs is open to debate. UniPalm's Mail-IT is an example of client + software that provides MAPI within the client and uses POP3 to access + the server. + + X.400 is the message transport defined for use between + telecommunications vendors and customers by the international + consortium of national standards bodies known as ISO. It roughly + corresponds to TCP/IP's SMTP and RFC822 header format. A consortium of + X.400 vendors (XAPIA) have developed an API for X.400 applications + called CMC. + + LDAP + + + + LDAP is a protocol (the Lightweight Directory Access Protocol) being + incorporated in some clients as an Internet way for the client to get + information about e-mail addresses from a server, i.e. to give you the + capability to type in someone's name and have the mail client software + retrieve the address from a server-based directory. LDAP also has + other uses. There are plans to incorporate LDAP clients into some IMAP + and POP clients. LDAP is essentially an Internet-based, simplified + X.500-like protocol and one of the original intentions of its creators + was to be gatewayed to X.500, thus giving relatively simple Internet + clients access to X.500 servers. Both LDAP and X.500 provide a method + for naming, retrieving, and searching fields in a directory, but do + not define the field-names or what is supposed to go in the fields. + Thus server/client interoperability requires further conventions. + + JAVA + + + + Java is a programming language currently (1996) touted as a tool for + web-based applications. It can affect the use of LAN protocols in a + number of ways: first of all, POP or IMAP clients can be written in + Java, using its cross-platform development capabilities to create + version for a number of platforms. Second, clients could be written as + "Applets", i.e. applications designed to be downloaded into web + browsers such as Netscape from a server. With such a design, a user + would only need access to a web browser to see their e-mail, e.g. drop + into a library and see your e-mail from one of its Internet-browser + kyosks. Applets are not normally allowed to access the + client-machine's disk files (which would result in too much risk when + browsing the Internet from the kind of people who develop computer + viruses), so such an application fits a little better into the IMAP + model (server storage of e-mail folders) than the POP model (client + storage of e-mail folders). Thirdly, Applets enable more practical use + of e-mail clients that use non-standard protocols rather than POP or + IMAP; interoperability is achieved because the server itself + distributes a compatible client applet right when the user accesses + the server. + _________________________________________________________________ + +List of Protocols and RFCs + + + + Note: for up-to-date information on the RFCs, get an index from an RFC + repository.
