by Wojciech Polak
GNU Anubis is an outgoing mail processor. It goes between the MUA (Mail User Agent) and the MTA (Mail Transport Agent), and can perform various sorts of processing and conversion on-the-fly in accordance with the sender's specified rules, based on a highly configurable regular expressions system. It operates as a proxy server, and can edit outgoing mail headers, encrypt or sign mail with the GnuPG, build secure SMTP tunnels using the TLS/SSL encryption even if your mail user agent doesn't support it, or tunnel a connection through a SOCKS proxy server.

DSPAM is a server-side anti-spam agent for UNIX email servers. It masquerades as the email server's local delivery agent and filters/learns SPAM using a Bayesian statistical approach which provides an administratively maintenance-free, self-learning Anti-Spam service. Each email is broken down into its most interesting tokens, each assigned a spam probability. All probabilities are then combined to produce a statistical probability of spam. This approach, applied to a mature corpus of email, has the potential to yield a 99.5% success rate with only 0.03% chance of false positives.

Python milter
Added 2004-04-21
by Stuart D. Gathman
The milter module for Python provides a python interface to Sendmail's libmilter that exploits all its features. Milters can run on the same machine as sendmail, or another machine. The milter can even run with a different operating system or processor than sendmail. Sendmail talks to the milter via a local or internet socket, and keeps the milter informed of events as it processes a mail connection. At any point, the milter can cut the conversation short by telling sendmail to ACCEPT, REJECT, or DISCARD the message. After receiving a complete message from sendmail, the milter can again REJECT or DISCARD it, but it can also ACCEPT it with changes to the headers or body.
