    I am using SMTP Virutal Server for IIS in Windows Server
    2003. Something else I should mention is the server is not
    in the DMZ. All of the correct ports are forwarded though
    (25 and 110). I went to 'Properties' on the Virtual Server
    and clicked the 'Access' tab. Then I added the IP ranges
    192.168.0.0/255.255.255.0, 10.10.0.0/255.255.255.128, and
    127.0.0.1 under the Relay Restrictions option. I've
    rebooted the server several times and it has not fixed the
    problem :(
