[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-2.11.3.html]
THIS IS NOT A DUPLICATE OF PATCHES THAT WERE RELEASED ON OCTOBER 13, 2014. THE HEADER PREPEND PATCH IN THAT SET IS REVERTED AND REPLACED WITH A COMPLETE SOLUTION.
Bugfix for Postfix 2.11, 2.10, 2.9 and 2.8:
Fix for configurations that prepend message headers with Postfix access maps, policy servers or Milter applications. Postfix now hides its own Received: header from Milters and exposes prepended headers to Milters, regardless of the mechanism used to prepend a header. This fix reverts a partial solution that was released on October 13, 2014, and replaces it with a complete solution.
Portability fix for Postfix 2.11:
Portability fix for MacOS X 10.7.x (Darwin 11.x) build procedure.
