hotmail email issues today?

2014-07-09 Thread Jared Mauch 
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.

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)..

 If you find users being dropped from mailing lists, it's probably a
 DMARC issue. Contact your mailing list vendor for appropriate patches.

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:mailauth-repo...@google.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.
