Hello all i wrote another anti SPAM framework called Decency, which works perfectly with Postfix. It's based on Perl POE and Mouse and is highly modularized / componentized. Since something last week, it has earned it's own website: http://www.decency-antispam.org Also on github: https://github.com/ukautz/decency The CPAN release is heavily outdated and will be renewed at the end of this month.
In short what it does: * It has a policy server, called Doorman, implementing techniques such as Greylisting, Geo Weighting, DNSBLs, Honeypot building, SPF and so on. * The second component is a content filter, called Detective, which implements third party filters (CRM114, DSPAM, ..), virus filters (for now: ClamAV) and also performs internal filtering, such as DKIM, deeper DNSBLs checks (Received-header) and also can act as an Archiving facility. * Its modular build, everybody can extend it. * Designed for single mail filter boxes as well as distributed structures. * Open source. * Simple configuration (imho). * More on the mentioned website.. I used it in production for about half a year. Currently it's going towards public stable version 0.2.0. Any feedback, critic, help, whatever is welcome. Greets from Berlin Ulrich
