Hi there,
It doesn't sound like an AMS issue, but maybe I'm wrong, so here it is..
I have a user whose getting all emails he sends to a particular address bounced back with the above message (Unable to obtain any valid MX records for the domain). The recipient says that his mailbox works just fine and that my user is the only one who can't reach him..
Does this make sense? What should I check?
Should I send you the domain name? PM is better for that?
Thanks!
David.
