Hello all!

I recently installed MailScanner on a server that I am responsible for 
to help reduce virus infections.

Things seemed to be working great, but then I started getting calls that 
outbound mail was not being delivered just to a select group of e-mail 
addresses.  Since these select group of e-mail addresses represented 
their significant customers, I turned MailScanner off.

My questions are:

1) Is there a way to exclude certain e-mail domains from outbound e-mail 
2) How would I diagnose why the mail was not being delivered?  (I think 
my maillog files show them leaving my server... could be that something 
on the scanned files shows up as problems to the incoming servers at the 
3) Any thoughts on why only certain domains would not get mail delivered?

Fedora release 8 (Werewolf)
Perl version 5.008008 (5.8.8)
MailScanner version 4.79.11
