I checked with Jared and he seems to misunderstand the meaning of the
DMARC failure reports he is getting. (I get them too, lots of them,
and file and ignore them.) They do not indicate any sort of delivery
problem.

Please do *not* change the DMARC settings for p=none since it degrades
the list mail and makes it much harder to tell who is sending each
message and who to reply to.
