(1) 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
(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 protocols POP
(probably not used anymore), POP2, POP3, IMAP2, IMAP3 (not used), IMAP4
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 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 the most-used POP, but POP2 is still used. POP3 has a
couple of optional extensions: one to avoid sending passwords, and one
to aid in reading bulletin boards.
IMAP2, IMAP3, IMAP4: 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. IMAP4 also extends IMAP to have many other features including
some of DMSP's.
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.
DMSP (aka 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".
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.
Disadvantages: there are a number of disadvantages associated with
the use of these protocols:
-since these methods do not dominate the industry, 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 often 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.
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. 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); SMF (Novell, part
of MHS). 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.
