I am having more mail problems than USPS, FEDEX, UPS put together LOL (joking)
Anyway, for every outgoing mail from my billing system ModernBill I'm getting this error (but it seems to be server side not internally in the software)
This is an example:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
user@yahoo.com
unrouteable mail domain "yahoo.com"
------ This is a copy of the message, including all the headers. ------
Return-path: <sales@mydomain.com>
Received: from nobody by server.mydomain.com with local (Exim 4.43)

This is happening to all domains regardless yahoo, msn, hotmail, gmail or non-free accounts. It is server wide from my expereince.
I have cPanel/WHM. In WHM's tweak settings, I have max emails per domain per hour set to 0 (default unlimited). I have "pop3 prevent floood..." off, "prevent user nobody from sending ...." off.
Spam assassin is off too. What else?
specs:
centos 3.3
cpanel 9.9.9 r-14
exim 4.3.4
