I work for a small company who forwards a lot of email for our clients. Our clients have their own domain name (which we control) and we set up exim to forward email on to their AOL, Yahoo, MSN, etc. accounts.

We have a couple hundred of these types of forwarders set up and would like to move them over to a new box (running exim) without doing it by hand.

The box is currently running Exim 4 and the new box should also contain version 4. The box also has CPanel installed on it.

Is there a main configuration file for each account that tells it how to forward email?
Has anyone done anything like this before?

I searched the forums for info on this topic but couldn't find anything.

Thanks for any help
