[Discuss] DMARC issue, Yahoo and beyond

[Stephen Ronan]

In case it's helpful, this was in a message sent on April 25 by 
Electric Embers <http://electricembers.coop> to the 
administrators of lists that utilize their service (previously 
they had for a while blocked yahoo users from posting):

"you'll be happy to hear that the problem we were having with 
Yahoo senders has been addressed with a software patch.

"Therefore, we are no longer blocking emails from Yahoo to 
Groups.

"You may notice a small difference in the From field on list 
messages from these senders (and now from AOL senders too), in 
which the sender's actual email address no longer appears, 
replaced by the address of the list itself.  This was the 
technical step that was necessary to avoid conflict with Yahoo's 
and AOL's new sender policy, but rest assured, replies are still 
directed to the original sender via the addition of a new 
Reply-To header."

p.s. they use the Sympa email list management software
