TL;DR: In never ending battle against SPAM and phishing attacks, some email providers are now using DMARC, rejecting or marking as SPAM email if the originating mail server doesn't match the authorized ones for the provider's service.
For example:
- Yahoo! is flat out rejecting e-mail from yahoo! mail users if it comes
from non-authorized servers.
- Google is marking e-mail from gmail users as SPAM if it comes from
non-authorized servers.
Unfortunately this breaks mailing list software like mailman (used for this list) which tries to make e-mail from the list appear as if it is coming from the original sender.
The changes that are required to fix the issue change the functionality of the list software in ways users may not like.
I found this out while applying DMARC for my my own domains.

Fun.
