When any account @domainA.com sends to a specific address (eg. [email protected]) it bounces. When they send to another address at the same account (eg. [email protected]) it goes through just fine. [email protected] has existed for a number of years now, [email protected] is relatively new, and has had this issue since created.
[email protected] can receive emails from any other domain, just not domainA.com.
I set up a forward address (call it [email protected]) which passes the email on to [email protected] as well as my work account which is on another domain. When [email protected] sends to [email protected], I receive the forwarded email, but [email protected] does not.
My questions.. More generally, what in the world is happening here? Specifically, is this issue something on the receiving end or the sending end? and how do I fix it if it's on the receiving end (which I control) or what do I tell the guys on the sending end to look for?
Here is the message received by domainA.com users when they send to the account:
