| qpsmtpd | Flexible SMTP daemon for network-level spam detection | Mehr ... |
This is a replacement SMTP damon which installs alongside a mail delivery
and transport system such as Exim, Postfix or Qmail, or used as an SMTP
proxy for a remote/DMZ MTA.
.
The qpsmtpd damon emphasizes spam detection during the SMTP transaction,
attempting to reach spam/nonspam decisions prior to accepting each message,
thereby eliminating much bounce/forgery blowback. It exploits its visbility
into the network transaction to detect certain behaviors often exhibited by
spam sending agents.
.
Qpsmtpd is written in Perl, with an extensive plugin API making it easy to
add new features or replace functional components.
