We have DMARC "munge from" configured on all mailing lists on lists.freebsd.org.

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

I've done a `config_list -o` and compared the output to a list that does munge correctly and I'm not seeing anything that would explain the problem.

When a poster from a DMARC-crippled domain tries to post to this list, I see a line in vette that the DMARC policy has been found. There are no messages in the error log.

Any idea what could explain this?  And how I could go about fixing it?

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.

Unfortunately, this is a live list with several thousand subscribers with various combinations of options and passwords configured so I can't simply blow the list away and create it again.

Can anyone think of something I may be overlooking?

Many thanks.
Philip
