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 this package.

this package contains the milter client, and a generic command line client for amavisd-new.
