Unfortunately not. An example I know of is Red Hat's corporate
E-mail, they use a third-party filter (Mimecast) as their MX which
then forwards to their custom domain on Gmail.

As a mailing list admin in some popular open source communities,
I've become all too familiar with these challenges. It doesn't help
that the situation changes month-to-month, so what you decide today
may suddenly stop working any moment and you're back to square one.

The cynic in me says that the mass freemail providers slipped these
policy frameworks in as a sort of Trojan Horse, promising to fix
"the spam problem" when their real goal was poisoning the well we're
all drinking from and then setting themselves up as the only safe
supply of drinking water. They're all too happy to propose standards
when they want other operators to do something, but then willfully
ignore those same standards whenever it suits their purposes.
