Making use of a number of open source technologies, including SpamAssassin, Exim, and MySQL, it provides an easy-to-use, but powerful method to filter email for your domain. Once configured, multiple domains can be added and administered with the Web interface. Email is scanned and scored, non-spam is then passed on to a destination email server, while spam is either blocked or quarantined. Individual users can log in and review their quarantined email, and manage their settings through the Web-based interface.

gateway with user and admin
Web interfaces, a quarantine system, and support

uses Bayes, RBLs,
Spamassassin, MailScanner, and ClamAV.
Synspam uses Netfilter NFQUEUE to catch the source IP address of any machine connecting to your mail server, running multiple tests against it (RBL check, regexp on the reverse name, etc.) before forwarding the connection to the MTA. In order to have as few false positives as possible, a scoring system is used. If the source IP address is believed to be a spammer IP address, the connection can be dropped. There is a dry run mode if you just want to test it, which is the default.

Spampig DnsblCheck takes the IP address of a mail server and looks it up in common blacklists and whitelists. The program tests against the major block lists from Spamhaus, SORBS, Spamcop, Barracuda, UCEProtect, and others. In addition to blacklists, it also checks against IP address and domain name whitelists and even checks PTR record integrity. The program returns results quickly, typically in less than a few seconds. If you don't get results quickly, it indicates you may have DNS problems and knowing this can also be useful. This application can be useful to spam fighters and email users who are struggling to find out why their messages are being blocked.

pgl4rbl implements a Postfix policy server that mixes two widely used techniques: greylisting and RBL (DNS blacklists). The idea is that greylisting is applied only to SMTP clients that match a RBL; this means that normal clients are not delayed (such as with a normal greylisting implementation), and RBL false positives do not cause problems (like when outright blocking them at the SMTP level).
