Hello,

I recently transferred my accounts from one server to another (cpanel based) , and everything worked fine except the following. All accounts' email addresses are getting the following error:

This message was created automatically by mail delivery software (Exim).

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:

postitby@localhost.localdomain
(generated from postitby@postitbyfax.com)
unrouteable mail domain "localhost.localdomain"


This is a problem with exim, and I am unsure how to go about fixing it. If anyone has any suggestions, it would be appreciated!

Thanks!

Do you mean Ensim?

Nope! Exim. It is the email program that Cpanel based servers use. Sorry for being unclear.

So sorry, my bad!

Check out the MX records in the DNS first and see if it's in the local domains of the exim config.
