by Matt Pulver
Pine Privacy Guard is a small Perl script used to interface Pine and GnuPG for the secure exchange of email. It allows Pine users to conveniently encrypt, decrypt, clear-sign, and verify clear-signed email. Other features include the secure storage of secret key passphrases during a session, alias support, simple installation, and compact, well-documented code.

by Nelio Souza Santos Filho
QMail Auditor provides simple a method for auditing emails. It is easy to configure and uses regular expressions as rules.

pop3spam
Added 2003-10-06
by Michael Velten
pop3spam is a POP3 client which connects to a POP3 server and deletes unsolicited mail. It's possible to check for messages that exceed a certain limit and to scan header lines for special patterns (regular expressions). If a message has been identified as unsolicited, it can be deleted directly from the POP3 server without the need to download it first. Eventually your normal mail-retrieval utility (e.g. fetchmail) can gather all (cleaned) mail as usual.

SPASTIC

by Keith Winston aka slippery
SPASTIC is an easy-to-use, powerful set of email filters to deal with Unsolicited Commercial E-mail (UCE), a.k.a. spam, using procmail. Some of its features are filtering based on header and/or body contents, predefined sets of filters to get started quickly, a whitelist to bypass filters, options on where to send spam, and an optional script to rotate the spam file periodically.

FirePay
Added 2003-08-11
by flamingcow
FirePay is an implementation of the HashCash/MIME (application/postage-hashcash) specification. HashCash is an anti-spam, anti-DoS system for email. The concept centers around the sender of the mail completing a computationally expensive task (in this case, generating hash collisions) that the recipient can verify very quickly. This allows the sender to "pay" for transport in CPU cycles, creating artificial scarcity. Programs are included to add payment to messages (for the sender) and to verify message payment (for the recipient).

The SpamBouncer
Added 2003-07-24
by BACbKA
The SpamBouncer is a set of procmail instructions that search the headers and text of your incoming email to see if it meets one or more of a list of conditions for probable spam. It will then either tag the suspected spam and return it to your main incoming mailbox, tag the suspected spam, delete spam from known spam sources, and file suspected spam in a separate folder, send a simulated MAILER-DAEMON daemon "bounce", complain to the "upstream providers" of known spammers or spam sites/domains, etc.

MailSleuth Email Management Package
Added 2003-07-14
by TurboTas

Spammer
Added 2003-07-14
by Aleksandar Milivojevic
Spammer is an anti-spam mail filter for sendmail. It uses libmilter to communicate with sendmail. Spammer checks client IP addresses as well as all IP addresses (and everything that looks like an IP address) in Received headers against a DNSBL database.

Active Spam Killer
Added 2003-07-03
by Marco Paganini
Active Spam Killer (ASK) protects your email account against spam by confirming the sender's email address before actual delivery takes place. The confirmation happens by means of a "confirmation message" that is automatically sent to all "unknown" users. Once the sender replies to that message (a simple reply will do), future emails from that person will be delivered immediately. You can also specify (regexp) addresses to be immediately accepted, rejected (with a nastygram) or ignored. The package also includes a utility to scan your old mailboxes and generate a list of emails to be accepted automatically.
