kuvert
Added 2002-05-08
by Alexander Zangerl
kuvert automatically signs and/or encrypts outgoing mail using the PGP/MIME standard (rfc2015), based on the availability of the recipient's key in your keyring. It does not store passphrases on disk, but keeps them in memory; if available, it prefers to store passphrases with quintuple-agent. It works as a wrapper around your MTA.

Secure Instant Messaging
Added 2002-05-07
by Sonny Rao
Secure Instant Messaging is a transparent encryption module for Gaim. It uses OpenSSL to encrypt/decrypt plaintext messages and base64 encoding to convert the encrypted messages to ASCII text.

AMaViS "Next Generation"
Added 2002-05-07
by Hilko Bengen
AMaViS-ng is a modular rewrite of amavisd and amavis-perl. It scans email for malicious code inside attachments and archive files, stopping delivery if malicious code is found. It supports integration of several third-party virus scanners and integrates nicely into several MTA setups. Unlike amavis-perl and amavisd, there is no need for build-time configuration.

Anubis
Added 2002-05-06
by Wojciech Polak
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 or WinGate proxy server. It also supports anonymous remailers.

Tagged Message Delivery Agent
Added 2002-04-24
by Jason R. Mastaler
The Tagged Message Delivery Agent (TMDA) reduces the amount of SPAM/UCE (junkmail) you receive. It combines a "whitelist" (for known/trusted senders), a "blacklist" (for undesired senders), and a cryptographically-enhanced confirmation system (for unknown, but legitimate, senders).

Milter-Virus
Added 2002-04-24
by Thomas Lussnig
Milter-Virus is a wrapper which allows you to use virus scanners like F-Prot in sendmail. It filter incoming and outgoing mail. The configuration file allows chaining of scanners and blocking of certain bad double file extensions

Mikrop
Added 2002-04-02
by volkan
Mikrop is a small, easy to install program for mail servers to scan incoming email. It uses third party virus scanners, and is currently integrated with the Postfix MTA.

keystory
Added 2002-04-02
by Frank J. Tobin
keystory, by analyzing email history, gathers data on the usage of OpenPGP signatures, and provides information to imperfectly, but practically complement the web of trust, answering questions such as "What keys has foo@bar.baz.com used, where and when?"

DisSpam
Added 2002-03-20
by Mina Naguib
DisSpam is a personal solution to combat spam (i.e. not for mailservers/ISPs). It is a Perl script that removes spam from POP3 mailboxes based on RBLs such as orbz.org. It runs through cron and uses a very simple configuration file.

Smtpblock
Added 2002-03-05
by David Bellizzi
Smtpblock is a tool that parses your UNIX mail log. When new mail messages are detected it performs a SMTP relay test to determine if the remote host allows the relaying of third party mail. If the remote host relays third party mail, Smtpblock creates a firewall rule to block access to the local host's SMTP port. Smtpblock keeps track of each remote host it detects and remembers it's test status and time when it will need to be rechecked, thereby reducing the need to constantly check every host sending mail to the local system. Seperate user definable time limits can be set for hosts that have passed and hosts that have failed. Failed hosts that are rechecked and pass will have it's corresponding rule removed and have it's status changed. Smtpblock will only check hosts that have open SMTP ports. All hosts with closed smtp ports will be blocked if listed in any of the defined RBLs. Smtpblock can be run as a daemon continously checking the UNIX mail log or as a stand alone program parsing the entire log file. Hosts can be manually checked, blocked or unblocked via command line options.
