The Qmail virus scanner (QScan) is a mail filter for Qmail that scans incoming messages using the Clam Antivirus engine, immediately rejecting infected content. It is designed to be minimalistic, yet extremely fast and secure, and uses multiple pipes instead of the traditional temporary files and privilege separation. Originally developed for the Sophos Antivirus, this port is patched to work in conjunction with the ClamAV daemon. WWW: http://www.pureftpd.org/project/qmail-antivirus
