What's New in version 2.7.0
  • 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).
