-Introduction
-
-   
-   
-   There are advantages to having a central server receive the mail
-   destined to desktop computers and having the desktop computer collect
-   the mail from the server on demand:
-     * Your desktop computer may be down quite a bit and less network
-       bandwidth and less of the processing resources of the sending
-       computer are used if the computer receiving your mail is ready to
-       receive.
-     * Some people use more than one desktop computer to read mail.
-     * A desktop computer may not have the resources to store all the
-       mail you receive.
-     * It can make your e-mail address more like other users'.
-       
-   
-   
-   The easiest way to "implement" this is to run the central mail server
-   like any multi-user system: let people sign on to it and use some mail
-   utility. 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.

-Capabilities of Well-known mail clients
-
-   
-   
-   This section covers what I've been able to find out so far about the
-   well-known mail clients' ability to retrieve mail from a POP or IMAP
-   server.

-Client                       POP3           IMAP          MIME
-------                       ----           ----          ----

-Notes:
-(-) Announced early 1996: target delivery: 4th quarter 1996.
-(=) CE plans to rename the successor to their current client
-    QuickMail LAN, while introducing both a free and a commercial
-    POP3 client, then upgrade the commercial POP3 client to also
-    support IMAP.
-(*) DaVinci SMTP eMAIL: I'm not sure if this is different from
-    the normal DaVinci client.
-(+) Requires Internet Mail Client for Exhange, downloadable from
-    http://www.windows.microsoft.com or included in "Microsoft Plus".
-(&) qp/base64
-(%) Planned for Netscape 4.0
