ANL just rolled out spf, dkim, and dmarc handling for emails. I've heard that 

mailman lists don't play with these new requirements. I've spent this past week 

reconfiguring postfix on my machines and noticed that protection.outlook.com 

marks my outbound emails as having failed dkim even though gmail says it passed.



Coud these be related?
