This is absolutely correct. As an admin that manages a CHM list on
Google, I agree that the problem is NOT with Google Gmail per se.
They are merely enforcing what they promised to do months ago.
Enforce the DMARC policy. Here's a typical response from Google when a
mail server does not follow practices initiated to reduce SPAM (actual
domain hidden by me with xxxxxx.xxx):
-----------------------------------------------------------------------
host gmail-smtp-in.l.google.com [173.194.203.27]
SMTP error from remote mail server after end of data:
550-5.7.1 Unauthenticated email from xxxxxx.xxx is not accepted due
to domain's 550-5.7.1 DMARC policy. Please contact the administrator of
xxxxxx.xxx domain 550-5.7.1 if this was a legitimate mail. Please visit
550-5.7.1  https://support.google.com/mail/answer/2451690 to learn
about the 550 5.7.1 DMARC initiative. q12si89233361pgc.52 - gsmtp
-----------------------------------------------------------------------

BTW, this typically happens when an email is posted to an email server
which is then redirected to Gmail via another server.

More and more mail systems will be enforcing DMARC policies - so it
would be good to make sure your ISP is setup correctly.

FYI - I use MANY email vendors (yahoo, comcast, arrl, acm, any my own
bickleywest.com, cerfnet.net, cerfnet.org, etc.) and ALL conform to the
DMARC policy and have no issues sending to or receiving mail from gmail.

Cheers,
Lyle
