postfix
High-performance mail transport agent
Postfix is Wietse Venema's mail transport agent that started life as an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.
exim4-daemon-heavy
Exim MTA (v4) daemon with extended features, including exiscan-acl
Exim (v4) is a mail transport agent. This package contains the exim4 daemon with extended features. In addition to the features already supported by exim4-daemon-light, exim4-daemon-heavy includes LDAP, sqlite, PostgreSQL and MySQL data lookups, SASL and SPA SMTP authentication, embedded Perl interpreter, and the content scanning extension (formerly known as "exiscan-acl") for integration of virus scanners and spamassassin. The Debian exim4 packages have their own web page, http://wiki.debian.org/PkgExim4. There is also a Debian-specific FAQ list. Information about the way the Debian packages are configured can be found in /usr/share/doc/exim4-base/README.Debian.gz, which additionally contains information about the way the Debian binary packages are built. The very extensive upstream documentation is shipped in /usr/share/doc/exim4-base/spec.txt.gz. To repeat the debconf-driven configuration process in a standard setup, invoke dpkg-reconfigure exim4-config. There is a Debian-centered mailing list, [email protected]. Please ask Debian-specific questions there, and only write to the upstream exim-users mailing list if you are sure that your question is not Debian-specific. You can find the subscription web page on http://lists.alioth.debian.org/mailman/listinfo/pkg-exim4-users
exim4-daemon-light
lightweight Exim MTA (v4) daemon
Exim (v4) is a mail transport agent. This package contains the exim4 daemon with only basic features enabled. It works well with the standard setups that are provided by Debian and includes support for TLS encryption and the dlopen patch to allow dynamic loading of a local_scan function. The Debian exim4 packages have their own web page, http://wiki.debian.org/PkgExim4. There is also a Debian-specific FAQ list.

rmail
MTA->UUCP remote mail handler
Rmail handles mail received via uucp and passes it to the local sendmail (or workalike). This version comes from the sendmail source package and the only change is the call to sendmail (from -obq to -obi).
courier-mta
Courier mail server - ESMTP daemon
The Courier mail transfer agent (MTA) is an integrated mail/groupware server based on open commodity protocols, such as ESMTP, IMAP, POP3, LDAP, TLS, and HTTP. Courier provides ESMTP, IMAP, POP3, webmail, and mailing list services within a single, consistent, framework. This package provides an ESMTP daemon which uses the Maildir format as native storage format, supports IPv6, implements SMTP extensions for mailing list management and features integrated mail filtering. It can function as an intermediate mail relay, relaying mail between an internal LAN and the Internet, or perform final delivery to mailboxes. ESMTP over TLS is handled by the regular ESMTP daemon in conjunction with the TLS wrapper.
masqmail
mail transport agent for intermittently connected hosts
Masqmail is an MTA (mail transport agent) and POP3 client for hosts with no permanent network connection, such as home network servers or notebook computers. It has special support for connections to different Internet Service Providers. In these cases, Masqmail is a slim replacement for full-blown MTAs such as Sendmail, Exim, Qmail or Postfix. The POP3 client can be a small replacement for other full-featured tools like Fetchmail.
exim
The exim mail transfer agent
sendmail
powerful, efficient, and scalable Mail Transport Agent (metapackage)
Sendmail is an alternative Mail Transport Agent (MTA) for Debian. It is suitable for handling sophisticated mail configurations, although this means that its configuration can also be complex. Fortunately, simple things can be done easily, and complex things are possible, even if not easily understood ;) Sendmail is the *ONLY* MTA with a Turing complete language to control *ALL* aspects of delivery! Sendmail provides Security and SPAM/UCE/UBE protection via several means. Sendmail includes *no* Mail User Agents (MUA), you'll have to pick from the plethora of available MUAs (mutt, vm, etc.) This package supports REGEX, DB, NIS, NIS+, LDAP, DNS maps, and has enabled TCPWrappers, IPv6, LockFile, SMTP AUTH(SASL), STARTTLS(SSL). This package is to make installation/upgrading easier (Do NOT delete it)
