    You mention dequeue - do you mean your ISP is using ETRN/etc? If so, your
    inability to telnet to your Exchange server on port 25 from the Internet
    doesn't matter. You're pulling the mail down, not receiving it directly. As
    long as you aren't blocking outbound ports you should be able to do whatever
    you want if it originates inside your network.

    What happens when you try to dequeue? What are your settings, and what have
    you tried?

    Note that you might get more help in microsoft.public.windows.server.sbs. I
    personally don't like multihomed DCs even when ISA is in use on a network
    (just my view) but there could be something in your SBS setup that's gone
    wacky.
