We have DMARC "munge from" configured on all mailing lists on

This week, I learned that one of our lists is not actually munging
though.

Another data point: to experiment, I added ^.*@yahoo\.com$ to
dmarc_moderation_addresses for this list.  It still doesn't munge.

Every other list on our system "just works".  This one is refusing
to cooperate.


I suspect this list has a pipeline attribute defined[1] and the list's
pipeline does not include SpamDetect or possibly CookHeaders.

What does

bin/dumpdb lists/LISTNAME/config | grep -A24 pipeline

show?

Good Morning,

I couldn't help noticing this thread since I am dealing with DMARC
issues at the moment.  May I use this forum to ask: Which approach is
better in any given scenario between "Munge From" and "Wrap Message"
(i.e. a little insight on when one is a better choice over the
other)?

In my experience, "wrap message" has the same downside as digests ... people will reply to the wrapper rather than the wrapped message (as they would reply to the digest rather than to an individual message within) and break the thread for everyone else.

Very few mail clients seem to support replying to nested messsages.

Munging appears to strike the right balance between frustration and functionality.

At the end of the day, DMARC still breaks the mailing list experience. We can only try to mitigate the damage.

Philip
