    Hello Everyone,

    I'm having a problem with my local workstation SMTP server being able to
    send messages out through the Exchange server on our 2003 SBS server.

    I'm working with Microsoft's CDO component (CDONTS or CDOSYS, I get the
    same results) on a Windows XP workstation, Windows 2003 SBS server and
    Exchange 2003.

    I have set up the SMTP service on the workstation, I imagine the SMTP
    service on the workstation should hand the message off the the exchange
    server and the exchange server would send the message out. I've had
    this work in environments that I didn't set up myself so I know its

    But now I'm stuck setting up the environment and it isn't working as I'd
    hoped. If I send a message to an internal and external email address
    neither recipient receives the message. I can see the messages in the
    smtp service's \mailroot\queue folder. If I reboot the machine the
    message is received at the external email address, but not the internal

    So my two problems:

    1)Messages not going out until the workstation is rebooted
    2)Message sent to internal addressee not received at all.

    Any suggestions?

    If you're running an SMTP server on your workstation you
    can but you don't have to relay through your Exchange

    - You configure your Workstation SMTP to relay through
    Exchange, you need to configure your Exchange SMTP to
    support relaying for your Workstation's IP address.

    - If you decide to send directly to the Internet without
    relaying through Exchange, you need to configure support
    for outbound SMTP on your FW, and what you specifically
    have to do will depend on whether you are running ICF or
