With the help of Perry, Postfix 2.2.5 is now in the base system. The two=20
new major features are TLS and IPv6 support. TLS will be disabled with
MKCRYPTO=3Dno and IPv6 will be disabled with MKINET6=3Dno.

Please test!


Main changes with Postfix version 2.2

This is a summary of the changes. These and more are detailed in
the following sections of this document.

- TLS and IPv6 support are now built into Postfix, based on code
from third-party patches.

- Extended query interface for LDAP, MySQL and PostgreSQL with free
form SQL queries, and domain filters to reduce unnecessary lookups.

- SMTP client-side connection reuse. This can dramatically speed
up deliveries to high-volume destinations that have some servers
that respond, and some non-responding mail servers.

- By default, Postfix no longer rewrites message headers in mail
from remote clients. This includes masquerading, canonical mapping,
replacing "!" and "%" by "@", and appending the local domain to
incomplete addresses.  Thus, spam from poorly written software no
longer looks like it came from a local user.

- When your machine does not have its own domain name, Postfix can
now replace your "home network" email address by your ISP account
in outgoing SMTP mail, while leaving your email address unchanged
when sending mail to someone on the local machine.

- Compatibility workarounds: you can now selectively turn off ESMTP
features such as AUTH or STARTTLS in the Postfix SMTP client or
server, without having to "dumb down" other mail deliveries, and
without having to use transport maps for outgoing mail.

- Remote SMTP client resource control (the anvil server).  This
allows you to limit the number of connections, or the number of
MAIL FROM and RCPT TO commands that an SMTP client can send per
unit time.

- Support for CDB, SDBM and NIS+ databases is now built into Postfix
(but the CDB and SDBM libraries are not). [disabled on NetBSD]

- New SMTP access control features, and more.
