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 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 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
