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, SMTP has a method to initiate reception, i.e. the "TURN"
command, but the method has problems, 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. Among other features
IMAP also allows mail on the server to be placed in server-resident
folders. 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. IMAP2bis is an extension of IMAP2 which is
still in use. Among other things, it made servers cognizant of the
MIME-structure of a message. IMAP4 is a refinement and extension of
IMAP2bis, and while it may still be in use somewhere, IMAP4rev1, which
makes necessary corrections to a few problems with IMAP4 as
documented, has replaced it (it was given a new designation to allow
you to demand it by name) and it is suggested that IMAP4-non-rev1
support be dropped from servers & clients in favor of IMAP4rev1.
IMAP4(rev1) also extends IMAP to have many other features including
some of those associated with DMSP.
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 (4/97), there are a many more POP than IMAP client
implementations and an Internet Service Provider is much more likely
to provide POP3 service than any kind of IMAP. POP3 is an Internet
Standard whereas IMAP4rev1 as of 2/97 is a Proposed Standard. But
interest in IMAP is growing with big-time software houses announcing
support. IMAP4rev1 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.
ESMTP ETRN
ETRN, which is documented in RFC 1985, is a modified version of the
original SMTP TURN command which is allowed as an option in Extended
SMTP (ESMTP). It provides a similar functionality to POP.
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 IMAP4, 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 IMAP4'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 IMAP4, 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
* Web
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.
Mail servers are now available that offer e-mail through normal web
interfaces, i.e. HTTP & HTML. In this case, your web browser is your
client. Potentially, a server could be built that allows reading from
any web browser software. Some kind of authentication is necessary.
Another trend is web servers that act as POP-to-web gateways or
IMAP-to-web gateways. The client is still just a browser: perhaps a
JAVA-enhanced interface is offered, perhaps not. If the server has a
mail store, it is acting as a whole mail system and if it can receive
SMTP mail, requires no other server. But suppliers of mail services,
wanting their systems to be universal, can have them pick up mail from
a POP server or an IMAP server, perhaps at the client's discretion. In
the case of IMAP, the server can be written so as to leave stored mail
on the IMAP server, or it can support both "remote" and "local"
folders, in this case, "local" meaning on the web server rather than
the IMAP server. Web-based e-mail has a lot of appeal: since a browser
is sufficient as a client, the clients are already deployed much more
widely than any specific e-mail client. Some organizations may well
try to offer a mail-specific client for on-site use and web access to
the same mail store for remote access.
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.

Key and Other Issues
(a) What are the common extensions to POP3 and which clients/servers
support them?
POP3k - Kerberos
POP3a - AFS Kerberos
POP3x - ?
POP3t - xtnd xmit facility--allows client to send mail through additional
POP commands, thus allowing server to verify/log source of mail.
POP3r - APOP
POP3s - RPOP
POP3m - ?
POP3u - with UIDL command.
(b) What DOS protocol stacks are supported?
MS-DOSm - Lan Manager
MS-DOSn - NDIS Drivers
MS-DOSl - Lan Workplace for Dos
MS-DOSs - Sun PCNFS
MS-DOSp - Packet Drivers
MS-DOSo - ODI Drivers
MS-DOSi - IPXLink
MS-DOSf - FTP Software PC/TCP
MS-DOSk - KA9Q I think
MS-WIN? - similar
MS-WINw - WinSock compliant
MS-WIN5 - Windows 95
WIN3 - Windows 3.x winsock
WIN3/95/NT - Windows 3.x Winsock, Windows 95 and Windows NT
WIN3/95 - Windows 3.x Winsock and WIndows 95
NetWare3 - NetWare 3.x
NetWare4 - NetWare 4.x
NetWare34 - NetWare 3.x and 4.x
PHP3 - written in PHP scripting language.
Perl - written in Perl scripting language.
Java - written in Java programming language.
JavaApp - written as a Java Applet.
(c) Other notes
IMAP1 - Original IMAP: I've heard that MacMS actually uses a unique
dialect of it. Definitely obselete, unsupported, discouraged.
IMAP2b - IMAP2bis: name applied to various improved versions of IMAP2.
This development effort culminated in IMAP4.
IMAP24 - IMAP2 or IMAP4
fshare - uses file sharing.
IMAPb4 - IMAP2, IMAP2bis, or IMAP4.
IMAP41 - IMAP4rev1
MAPI - Microsoft's Messaging API
HTTP - Web-based e-mail.
MAPIs - Simple MAPI.
VIM - Lotus's Vendor Independent Messaging API
CMC - XAPIA's Common Message Calls API
AOCE - Apple Open Collaborative Environment
PROP - System-specific proprietary protocol
FCP - SoftArc's proprietary client-server protocol.
Unix/X - X Windows based
Unix/XM - Motif based
Unix/XO - OpenWindows based
UnixSHA - Solaris, HPUX & AIX
PSS - PROFS Screen Scraper
sumex-aim.stanford.edu* - almost dead as of 7/13/95, to be replaced by
info-mac.org.
Metamail - a package with which MIME messages can be processed from
basically any Unix-based mail client.
POPGate (Stalker Software) - gateway to/from Stalker's CommuniGate
system: enables both use of POP3 to get software from a POP3 server
for use within a CommuniGate community, and to allow POP3 clients to
retrieve mail from a CommuniGate server.
DigUNIX - Digital Unix
Solaris - Solaris 2.x
peer - peer-to-peer mail system
gtwy - e-mail gateway of some kind: a system that moves e-mail between two
different systems/areas. Among other things, a add-on to a
proprietary mail server that made it act as a POP or IMAP server or
that made it exchange e-mail using SMTP could be called a gateway.
(d) IMAP/MAPI adaptors:
Wollongong's Pathway Access 7/12/94
[email protected]'s Mail-IT 7/12/94
(e) IMAP/POP3 adaptors:
Included with NCD Z-mail 4.0 for Windows 9/14/95
