First of all, thank you for your interest in the Postfix project....
First of all, thank you for your interest in the Postfix project.
What is Postfix? It is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program.
Postfix attempts to be fast, easy to administer, and secure. The outside has a definite Sendmail-ish flavor, but the inside is completely different.
This website has information about the Postfix source code distribution. Built from source code, Postfix can run on UNIX-like systems including AIX, BSD, HP-UX, Linux, MacOS X, Solaris, and more.
What's New in This Release:В· 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.
В· 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.
В· 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.
В· 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).
System Requirements:No special requirements.
Program Release Status: Minor Update
Program Install Support: Install and Uninstall
