msmtp -- An SMTP client
msmtp is an SMTP client that can be used as an "SMTP plugin" for Mutt and
probably other MUAs (mail user agents). It forwards mails to an SMTP server
(for example at a free mail provider) which does the delivery.
To use this program, create a configuration file with your mail account(s) and
tell your MUA to call msmtp instead of /usr/sbin/sendmail.
Features include:
* SMTP AUTH methods PLAIN, LOGIN and CRAM-MD5
(and DIGEST-MD5 and NTLM when compiled with GSASL support)
* TLS encrypted connections
(including server certificate verification and the possibility to send
a client certificate)
* DSN (Delivery Status Notification) support
* IPv6 support (on systems that support it)
* support for multiple accounts
* sendmail compatible exit codes (which most MUAs understand).
Note: you may want to install mail/msmtpqueue - queuing support for msmtp.
This is the second module produced by the "Perl Email Project", a
reaction against the complexity and increasing bugginess of the Mail::*
modules. It delivers an email to a list of mailboxes.
This module allows you to build HTML emails, optionally with a
text-only alternative and embedded media objects. For example,
an HTML email with an alternative version in plain text and
with all the required images contained in the mail.
PHP email transport class featuring multiple file attachments, SMTP
servers, CCs, BCCs, HTML messages, and word wrap, and more. It can
send email via sendmail, PHP mail(), or with SMTP. Methods are based
on the popular AspEmail active server component.
Policyd-weight is (as the name says) a weighted policyd for Postfix.
It uses HELO, MAIL FROM and the MTA IP address for scoring their
correctness. It also uses definable DNSBLs and RHSBLs in a scored fashion.
implements Yahoo!, Inc.'s DomainKeys draft standard for signing
and verifying e-mail messages on a per-domain basis.

This automatically tacks a message onto the end of messages as they're being
sent from SquirrelMail. It functions just like the Hotmail/Yahoo/etc. mail
services, with all of their little 'get your own free hoojamajiggy' messages.
SmtpRC is a fully configurable, multithreaded open mail relay scanner.
It supports scanning of IP blocks, and can print the results to a Web
page. It is intended for Systems Administrators to check IP blocks
under their control
[ excerpt from developer's site ]
SpamOracle, a.k.a. "Saint Peter", is a tool to help detect and
filter away "spam" (unsolicited commercial e-mail). It proceeds
by statistical analysis of the words that appear in the e-mail,
comparing the frequencies of words with those found in a user-provided
corpus of known spam and known legitimate e-mail. The classification
algorithm is based on Bayes' formula, and is described in Paul
Graham's paper, A plan for spam.
This program is designed to work in conjunction with procmail. The
result of the analysis is output as an additional message header
X-Spam:, followed by yes, no or unknown, plus additional details.
A procmail rule can then test this X-Spam: header and deliver the
e-mail to the appropriate mailbox.
The xmailbox program displays, by default, an image of a mailbox. When
there is no mail, the image shown is that of a mailbox with its flag down.
When new mail arrives, the image changes to that of a mailbox with the
flag up, its door open and a letter visible inside. It can also optionally
play a sound through the sound-card. The NCD audio server, the rplay sound
package, FreeBSD Sun-compatible audio drivers, and an external sound player
program are supported. By default, pressing any mouse button in the image
forces xmailbox to remember the current size of the mail file as being the
``empty'' size and to change its image accordingly. In addition, the user
can optionally invoke his/her favorite mail retrieving program.
