First, apologies if this has been discussed before. I run a number of mailman lists on a Centos 6 platform and mailman 2.1.12-25. This version was updated in July as follows:
https://rhn.redhat.com/errata/RHSA-2015-1417.html and included fixes for a number of DMARC issues. Including "... With this update, domains with a "reject" DMARC policy are
Normally the lists we use are configured with reply_goes_to_list and anonymous_list is off. We have done some testing, and we have not been able to identify settings that will
retain reply_goes_to_list functionality and turn on DMARC Mung.
Generally what happens is that the first message is successfully sent to a yahoo.com address and this user can reply to the message as normal. However, mailman adds the original
sender to the reply-to meaning that when another user replies to this message reply_goes_to_list doesn't work.
It seemed to me that a small modification to CookHeaders.py could prevent the adding of the original sender email to "Reply-To"
# We also need to put the old From: in Reply-To: in all cases.
# Set Reply-To: header to point back to this list. Add this last
seemed like a good place to look, but before I try to debug commenting out this didn't prevent the addition of the original sender to Reply-To I would ask for some advice !!
any assistance would be very helpful!! (it maybe that changing the order of addresses in the Reply-To field would all reply_goes_to_list would work?)
