Huh. This is not what I expected. I think this means that gmail.com
does not have a strict DMARC policy after all. So I was wrong to expect
rewriting for it.
(Just to be clear: it would be wrong to apply the google.com DMARC
policy to gmail.com because the MX host location does not matter for
this policy.)
Thanks,
Florian
