[Exim] Error recieving messages.

Whenever I recieve email, the lots just show this over and over for all
accounts.

2004-07-19 16:54:33 1BmhqI-0003An-9j == email@??? routing defer
(-51): retry time not reached

And the messages are never delivered for any of the accounts. Also unable
to send, and recieve no error messages back. Checked the queue and found
exim still seeing the old hostname, and not sending it to the right place.

Anyone else encounter these errors and know how to fix?

Thanks;

Jason
