IMPORTANT: read the documents in /usr/pkg/share/doc/postfix/ before
upgrading from Postfix 1.1.
Hightlights:
- MIME support (including 8bit->7bit conversion and more
accurate matching of MIME headers in message bodies)
- completely rewritten RBL client code
- smarter handling of DNS lookup errors in UCE restrictions
- virtual delivery agent without transport map for every domain
- a long list of other things that are meant to improve performance
or functionality without compromising what already existed.
