amavisd-new is a high-performance and reliable interface between MTAs and one or more contentcheckers, including virus scanners, and/or theMail::SpamAssassin Perl module. It talks to an MTAvia (E)SMTP or LMTP, or by using helper programs.No timing gaps exist in the design, which couldcause a mail loss. It is normally positioned at ornear a central mailer, not necessarily where theuser's mailboxes and final delivery takes place. License: GNU General Public License (GPL)Changes:
