Check if these domains are mentioned in /etc/localdomains and remove them. Restart bind and exim.

service named restart
service exim restart

Also tweak cpanel to prevent setup of common domains such as hotmail..etc.

You should also check your exim mainlog for errors when sending such an email and watch for messages/errors.
