OK, I know enough about exim to be really dangerous. Any idea how I set up exim to relay for only a limited set of
users? i.e. just the 3 or 4 test users to start.

Debian the way you ad email users is simply to add a system user and exim automatically adds the email user. I want to
know if it is possible to separate the 2. I will be one of the test users on the new email system and I would rather
remove my email account than forward all emails to the new server.
