    Hi! I am having difficulty confirming this for two reasons. Perhaps I am
    doing something wrong. I am running Norton Antivirus 2000 with poproxy.exe
    on MS Outlook 2000.
    poproxy.exe SEEMS to only bind to localhost (127.0.0.1) instead of my IP on
    the network (192.168.0.24). If I try to telnet to port 110 from another
    Windows machine, it cannot connect. If I try to telnet to 127.0.0.1 from my
    own machine, it connects fine. Once I did connect to it from localhost, I
    sent 269+ chars to it and only received back "-ERR". I did not experience a
    crash.

    Again, perhaps I'm doing something wrong.
