Google, Microsoft, and others are strengthening the DMARC requirements for email. 3rd party emails are getting hit as are others.
Here is one article on what is happening.

Google has similar announcements about email security tightening. Google is also shutting down googlegroups so if you are using that to access usenet you need to find a new host - like www.eternal-september.org
This is both good and bad - good because the tightening up of email requirements should knock out a lot of spam, and bad because an awful lot of people are going to be blown off of email and not have a clue how to recover...

Three days ago, Microsoft randomly started rejecting mail from this list, apparently as well as several others, as some sort of anti-spam measure. This caused a lot of bounces and messages about members getting unsubscribed.
It affected hotmail.com, outlook.com, live.com and perhaps a few other recipient domains.
I've proactively resubscribed everyone that seems to have been affected.
If you find list mail being routed to your junk folder, please follow the link to choose "Trust this sender" which may help this kind of thing from happening again. I have no clue what caused it, and apparently neither does Microsoft.
