Is yahoo doing the same thing for yahoo groups?
Yahoo doesn’t have to. Mail from a Yahoo group already has a Yahoo domain in
the From field - the group address.
Yahoo doesn't have to, but not for that reason. Yahoo groups don't put
the Yahoo domain into the From line. They leave the original sender's
address there (whether it's a Yahoo address or not). Or at least that's
how they were handling it the last time anyone posted to a Yahoo group
I'm subscribed to, though that was before this DMARC p=reject business
started.
I think the reason Yahoo groups don't have to rewrite the From line is
that even if the original sender uses an @yahoo address, passing the
message through a Yahoo groups server won't break the DMARC tests
because it's still a yahoo server and therefore "aligns" with the
original From address. Or so I understand it: Mark or somebody correct
me if I'm wrong?
But now I wonder what happens if a user with an @aol address posts to a
Yahoo group. Will it run afoul of AOL's p=reject policy? If I still
had an AOL address I'd be tempted to try this just to see what happens.
