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.
