I'm getting this error

Your message cannot be delivered to the following recipients:
Recipient address: email@example.com
Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550-"The recipient cannot be verified. Please check all recipients of this message to verify they are valid."
Remote system: dns;customerdomain.com (TCP|220.127.116.11|13280|18.104.22.168|25) (server.customerdomain.com ESMTP Exim 4.51 #1 Wed, 03 Aug 2005 12:31:32 -0400 )
I have domain number 1 pointing to domain 2. Domain 1 has a domain email forwarder setup as well to domain 2 correctly. Domain 2 does not have anything custom setup.
Default address on each domain is the default :fail:domain: as cpanel sets up automatically.
What could be wrong?
