Authentication:  I have all three methods of
authentication turned on.
Connection: All except list below - nothing in list
Relay Restrictions: Only the list below - which has the
IPs; allow all computers which succesfully authenticate to
relay is Checked.

Now I remember the problems I ran into:

All smtp traffic (port 25) was blocked between the allowed
IP's and the email server (someone installed a firewall
and blocked port 25 in order to combat worms and
zombies).  This doesn't sound related to your problem -
although you might want to make sure you can telnet to
port 25 on your mail server from inside your network.

The large IP ranges didn't seem to work - although I can't
recall confirming the problem.  I replaced the large
ranges with a bunch of small blocks: x.x.x.1
(255.255.255.0)  Then I rebooted and then everything
worked properly.

Hope this helps.

btw- exchange's Queue management might be worth the
switch, but I'm sure you'll need to solve this problem
first.
