A few weeks back upgraded from 10.3 to 10.4.4 and it broke something with postfix handling outbound messages from mailman. Posts to a list can get dozens of header lines with:
X-No-Auth: unauthenticated sender
They appear to be the last headers added (i.e. before them are the headers from the local MTA that received the message from my server)
I've been searching /reading up on postfix but so far I don't have a clue as to where to look. Anyone have any pointers or advice?
-----------------------------
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE
Linux 2.6.18-164.11.1.el5
10.4.4 Update #24, last updated at Mar 31, 2012 09:13 PM
Parallels Plesk Panel v10.4.4_build1013111102.18 os_CentOS 5
mailman 2.1.9-6.el5_6.1
postfix 2.8.4-11100518
PROBLEM DESCRIPTION
multiple "X-No-Auth: unauthenticated sender" headers added to outbound messages sent with mailman.
Does not seem to happen with other (non mailman) email.
mail logs look normal
ANY ADDITIONAL INFORMATION
The site uses a commercial anti-spam system (Precise Mail Anti Spam Gateway) that accepts the in bound port 25 connections and then forwards it to postfix on a different port. However this problem seems to be on the outbound side, regardless it worked before upgrading to 10.4.4 so something must have changed to break things.
