That's fixed in 2.1.18.

DMARC has forced mitigation responses. As far as I can tell, there are
no ways to deal with this that don't involve impacts on message
readability, replies or both other than not accepting messages From:
domains with DMARC p=reject.

And these are the same users who would never see an X-Mailman-* header.

Note: that there are reasons for wanting replies to go to the poster and
the list. E.g., the poster may be receiving digests so including her in
replies keeps her in the loop without her having to wait for the next
