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.

Changes:
Detection of nonstandard bounces was improved, allowing this release to kill more third-party backscatter without sacrificing reliable acceptance of genuine DSN and MDN. The backscatter processing rate was greatly improved by avoiding SA processing of killed bounces. A DKIM documentation section was rewritten to prompt more wide-spread use of DKIM signing by amavisd. A bug was fixed that could let the SMTP protocol get out-of-step when SMTP connection cache is enabled. Compatibility with SpamAssassin 3.3 (CVS head) was regained, and compatibility with Perl 5.10.0 was tested and confirmed.
