Qpsmtpd - Flexible smtpd daemon.

Qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core SMTP features, all functionality is implemented in small "extension plugins" using the easy to use object oriented plugin API. These plug-ins allow for the checking of recipients and senders, as well as virus scanning, spam checking, blocking lists (DNS and RHS), SMTP AUTH and TLS. SMTP.

The qpsmpd daemon was originally written as a drop-in qmail-smtpd replacement, but now it can not only be integrated with qmail but also with Postfix and Exim. qpsmtpd can also write messages to Maildirs or forward them to a remote host via SMTP.
