[Exim] helpon open relay

hello all,

I think our server might have us set upas an open relay. Is there anyone
that has experience with the exim 3.36 that comes with C Panel. Mabe some
documentation I can read on it. I'm new to EXIM, all my other servers have
qmail running on them. I'm looking to do eather pop b4 smtp or smtp auth
but I don't know where to begin to look. Any clues?

thank you for any help,
