I've seen that happen on several lists.

I disabled DMARC on my mail servers. I really like the concept but way 
way way too many false positives.

Mostly lists, but also what sometimes happens - primary MX for 
whatever.com is down so mail goes to their backup with then relays it to 
their primary when primary back up, but their backup MX obviously isn't 
in my SPF record and they have things mis-configured causing a DMARC 
trigger.

I like the concept but it seems to have too many problems in implementation.
