Procmail is a powerful Mail Delivery Agent (MDA) capable of sorting and filtering mail based on rulesets called recipes. It's rather *nix-centric, terse, mature, and proven. However, it is now unmaintained.

Procmail is a versatile mail delivery agent (MDA) for Unix-like systems. If features a simple language for articulating delivery rules (aka recipes) to sort, forward, manipulate, and otherwise process incoming email messages.

Procmail was created in the early 1990s by Stephen R. van den Berg. After his involvement waned, Philip Guenther took over as maintainer, and published some new versions at http://procmail.org/. However, this site is now dead, and as of 2010, Guenther recommends users to switch to alternative tools such as maildrop.

In spite of its age and security issues, Procmail remains popular in some environments.
