Anyone know what happened? I've started to see a large number of bounces from them (this caused a large number of people with their e-mail hosted there to be removed from mailing lists I host).
Offlist replies/pointers to what I'm doing wrong are welcome.
If you find users being dropped from mailing lists, it's probably a DMARC issue. Contact your mailing list vendor for appropriate patches.

I'm adjusting mailman now to do this hoping that's it. It's on the privacy->sender tab.
If you got unsubscribed from cisco-nsp or juniper-nsp this morning this is likely why.
(ugh, 56 lists to adjust)..

or let them drop and hopr they move to a standards-compliant email home.
they're not called yahoos for nothing.
it's not clear (to me at least) that hotmail has deployed any DMARC
config at all, actually:
$ dig txt _dmarc.hotmail.com +short
$ dig txt _dmarc.outlook.com +short
no results... but:
$ dig txt _dmarc.gmail.com +short
"v=DMARC1\; p=none\; rua=mailto:email@example.com"
Don't let that stop others from offering leftfield advice.
According to MailOP, Yahoo had acceptability issues as well this AM.
I suspect they started checking DMARC in the past 24 hours.
This impacts those who have "hotmail for their own domain" in addition to hotmail.com addresses.
