ASSP

The Anti-Spam SMTP Proxy (ASSP) server project is an Open Source, Perl based, platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify e-mail spam. ASSP is easy to set up because it requires only minor changes to the configuration of your your Mail Transfer Agent.

Features

Some ASSP's [Features] are:

  • Bayesian analysis
  • [Penalty_Box] (PB) trapping
  • Realtime Blackhole Listing [DNSBL]/RBL
  • [URIBL] (Uniform Resource Identifier Black Listing)
  • Multi-level [SPF] (Sender Policy Framework) validation and blocking
  • [SRS] (Sender Rewriting Scheme) fix-up
  • Session [Delaying/Greylisting] and connection response delaying
  • Sender validation and recipient validation ([LDAP])
  • Multi-level attachment blocking (based on block lists or allow lists)
  • As well as multiple RFC validation mechanisms.
