amavisd-new 1:2.6.5-0ubuntu3 (i386 binary) in ubuntu quantal

 AMaViSd-new is a script that interfaces a mail transport agent (MTA) with
 zero or more virus scanners, and spamassassin (optional).
 .
 It supports all common virus scanners (more than 20 different AVs), with
 direct talk-to-daemon support for ClamAV, OpenAntiVirus, Trophie, AVG,
 f-prot, and Sophos AVs.
 .
 AMaViSd-new supports all MTAs through its generic SMTP/LMTP filter mode
 (ideal for postfix and exim). It is faster and safer to use the SMTP/LMTP
 filter mode than using the AMaViS pipe client. It supports sendmail milter
 through the amavisd-new-milter package.
