Postfix 2.7.0 stable release available

[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-2.7.0.html]

Postfix stable release 2.7.0 is available. For the past several
releases, the focus has moved towards improving the code and
documentation, and updating the system for changing environments.

- Improved before-queue content filter performance. With
  "smtpd_proxy_options = speed_adjust", the Postfix SMTP server
  receives the entire message before it connects to a before-queue
  content filter. Typically, this allows Postfix to handle the same
  mail load with fewer content filter processes.

- Improved address verification performance. The verify database
  is now persistent by default, and it is automatically cleaned
  periodically, Under overload conditions, the Postfix SMTP server
  no longer waits up to 6 seconds for an address probe to complete.

- Support for reputation management based on the local SMTP client
  IP address. This is typically implemented with "FILTER transportname:"
  actions in access maps or header/body checks, and mail delivery
  transports in master.cf with unique smtp_bind_address values.

- The postscreen daemon (a zombie-blocker in front of Postfix) is
  still too rough for a stable release, and will be made "mature"
  in the Postfix 2.8 development cycle (however you can use Postfix     
  2.7 with the Postfix 2.8 postscreen and dnsblog executables and 
  master.cf configuration; this code has already proven itself).

No functionality has been removed, but it is a good idea to review
the RELEASE_NOTES file for the usual minor incompatibilities or
limitations.

You can find Postfix version 2.7.0 at the mirrors listed at

The same code is also available as Postfix snapshot 2.8-20100213.
Updated versions of Postfix version 2.6, 2.5 and perhaps earlier
will be released with the same fixes that were already included
with Postfix versions 2.7 and 2.8.
