Well its late and i cant get any of my admins to help out.

So might as well ask a question here. :)

Cpanel server doesnt send all email out and is keeping them in the que.

We get this error: Sender address rejected: Domain not found
Return to Mail Que.

If anyone can help with some suggestions to fix this problem soon it would be much appreciated.

The admins will be in in around 5 hours but it is Sunday so its not that i expected to be confronted with a problem i couldnt fix.

Kind regards
Elena
