    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.
