And in any event, my original post was a FYI, mainly concerned with the
interaction between Google's Gmail policies and _any_ system which
munges headers to deal with DMARC, as MM does - combined with the fact
that a lot of spammers these days seem to be sending mail over From
addresses which publish a DMARC p=reject policy. This is a particular
nasty combination which can effectively neutralize Gmail's spam

I'm not looking for advice from anyone on how to run FMP's mail system,
nor for admonitions to do a better job of spam blocking, so if that's
what you want to say, please email me personally because it's OT for
this list.

If anyone has insights into this issue that _don't_ relate to FMP's
email service, or which constitute constructive insights based on
knowledge and experience, I'd love to hear them. Otherwise, please just
leave it!
