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

Subject: hotmail email issues today?

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.
