[Exim] Sendmail out Exim IN... Wait it won't work anymore.

Alright small problem that shouldnt' be really hard for you guys since
you are all guru's compared to my know-how of exim.

I had sendmail on my server running before... all my web apps were using
it to send mail out.
I was wondering how to make exim replace what sendmail was doing before.

Anyone understand what I mean... if not I will clarify ... thanks again
