I have recently migrated to Exchange 2013 CU2 from 2010, and ever since then we have been unable to receive any email messages from Yahoo. Whenever someone sends an email, they will receive a delivery failure email in their inbox (see below) Unfortunately the error provides absolutely NO helpful information as far as I can tell, like what the heck does "unreachable for too long" mean, especially when I can receive mail from all kinds of other domains.
I have enabled email security on our Exchange 2013 servers, but I have no blocked domains, and I have added yahoo.com, yahoo.ca and ymail.com to the Content Filter Config bypassed sender domain list.
I am also trying to deal with yahoo, but they don't seem to get the problem!
