amavisd-new is a high-performance and reliable interface between MTAs and one or more content checkers, including virus scanners, and/or the Mail::SpamAssassin Perl module. It talks to an MTA via (E)SMTP or LMTP, or by using helper programs. No timing gaps exist in the design, which could cause a mail loss. It is normally positioned at or near a central mailer, not necessarily where the user's mailboxes and final delivery takes place.  [edit]  Less
