A head's up to all…

It looks like Google might be tightening up their message receiving checks.
Renaud's message went into my Spam folder at Google, with the explanatory
reason:

*Why is this message in Spam?* It has a from address in allard.it but has
failed allard.it's required tests for authentication. Learn more
<https://support.google.com/mail/answer/1366858?hl=en-GB&expand=5>


In particular:

- the DKIM signature failed to verify: "dkim=neutral (body hash did not
verify) header.i=@allard.it;"
- the SPF check from the envelope's RFC5321.MailFrom "@exim.org" address
gave a *neutral* result *but* its domain isn't in alignment with the "
allard.it" in the RFC5322.From address, which is a problem because…
- allard.it publish a DMARC record saying messages that fail both DKIM
and SPF checks should be rejected: "v=DMARC1\; p=reject\; sp=reject\;
pct=100\;" (DMARC requires the underlying SPF test to pass *and* the
domains of the RFC5321.MailFrom and RFC5322.From addresses to be in
alignment)

I know people have been expecting this to become a problem and it appears
to be here now. I suspect the Exim list's service needs to adapt to work in
the brave new world…

Cheers,
Mike B-)
