Hello,
Could anyone please provide me with a tutorial on enabling SMTP Authentication with Exim on a cPanel box. It currently seems that my server is openly relaying - and cPanel offers no control over the configuration of the mail server.

What I would like to do:
+ Allow unconditional relaying from mail originating from the server.

+ Force any other user to authenticate using same username & password as POP account.

I would appreciate any help in this or directions to an exim tutorial or configuration script.

Thank you,
Gerrit Lansing
