[Mailman-Users] DMARC mitigation failing on one list

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?

Many thanks.
