Subject: [MOPO] Yahoo Has Broken MoPo (and all internet mailing lists...)
To: MoPo-L@LISTSERV.AMERICAN.EDU
After a very long week with a torrent of e-mail bounce reports and mass
deletions of long-time MoPo subscribers from the listserv, the issue with Yahoo
e-mail accounts (and a few other domains) has become clear. I’m providing the
response I received from American University concerning this issue, which
includes 3 helpful links that go into great detail about the issue (for those
of you who are interested). Bottom line for now….Yahoo e-mail users need to
complain to Yahoo….and for now, subscribe with another e-mail account. Other
e-mail providers that appear to have also made the change are Gmail, Hotmail,
MSN and Comcast. I fear others may follow. ScottMoPo List Owner AU’s response:
L-Soft, the listserv vendor, advises:
"This problem is the result of a Yahoo policy change, and it is a situation
which has affected every mailing list provider. There have been a few write-ups
regarding it:
http://www.pcworld.com/article/2141120/yahoo-email-antispoofing-policy-breaks-mailing-lists.html
http://www.ietf.org/mail-archive/web/ietf/current/msg87153.html
https://wordtothewise.com/2014/04/brief-dmarc-primer/
The result is, among other things, that when a Yahoo user posts to a mailing
list using their yahoo.com email address, sites that support DMARC records will
reject the message, resulting in bounces.
My understanding is that this action by Yahoo is specifically a response to an
ongoing attack against Yahoo users attempting to compromise their accounts and
then send email from that Yahoo user to their contacts – Yahoo has been able to
block this outgoing spam through their own mail servers, but then ran into a
problem with the attackers using external mail servers to send the spam. Their
new DMARC policy helps put a stop to that, at the cost of various sorts of
inconvenience to their users, such as losing the
ability to participate in mailing lists.
So depending on how things progress we can hope that this new policy will
change or will go away. Certainly a number of people and organizations, L-Soft
included, are suggesting that this would be a good way for Yahoo to go."
At this point, Scott, it doesn't appear that there is anything we, or L-Soft,
can do, except have your users write to Yahoo and request they change their
policy.
