Email bounce back - (failure notice)

[tcong]

I receive a bounce back email when i tried to send email from plesk to exchange server. I use to be able to send email to the exchange but after i migrated to plesk i'm unable to send to exchange server.

Is it because of the xen2.com below is not a valid domain name? How and where can i change the domain name to a valid one?

Please advise.

Is this the only emil account you are having problems with or is this a single occurance?

Plesk has a Knowledge Base on that:
