amavisd-new-2.4.1 release notes

INCOMPATIBLE CHANGE WITH 2.4.0:

- notification templates incompatibility with 2.4.0 (but not with versions
  2.3.3 or older): major contents category numbers are renumbered due to a
  newly inserted category CC_SPAMMY; it affects the use of macro ccat_maj
  in templates (one field added), and only affect users which provide
  non-default templates based on 2.4.0 templates; older templates (2.3.3
  or earlier) are unaffected as they do not use macro ccat_maj;

amavisd-new-2.4.0 release notes

The most important changes since 2.3.3 at a glance:

  Delivery status notifications (DSN) are now supported, both as a SMTP
  protocol extension and in notifications. Header fields like X-Amavis
  and X-Spam are now prepended to mail header for DomainKeys compatibility.
  Configuration variables can be chosen based on mail contents category,
  which is now represented explicitly. A built-in macro expander is enhanced,
  providing new macros and call types. Added support for passive operating
  system fingerprinting with the use of p0f, supplying collected information
  as a header field to SpamAssassin. Provide compatibility with Net::Server
  0.91 and later.
