Looks like AOL is joining Yahoo in a joint effort to destroy significant parts of the internet.
According to this blog post: http://postmaster-blog.aol.com/2014/04/22/aol-mail-updates-dmarc-policy-to-reject/
, they are making the same change that Yahoo did. As such, this will cause any posts by AOL users to be rejected by Gmail, Hotmail, Comcast, Gmail, Yahoo, & AOL.
At the present time, my only course of action is to prevent AOL and Yahoo users from being able to post to any midrange.com lists.
If you use Yahoo or AOL, please consider switching to Gmail or Hotmail for midrange.com mailing list subscriptions.
