    Very helpful to be able to separately test the individual
    components of a message!

    I was getting a 550 problem with any recipients I tried. I
    changed the SMTP server's Relay Restrictions to allow all
    systems to relay. That solved the 550 problem, but
    messages are still getting hung up in the Queue folder.

    My test computer is at my home, on a Comcast (broadband
    cable) network. My computer doesn't have a DNS domain name-
    -only an IP address. Could that be causing a problem?

    Thanks--

    This pointed me to an article that essentially said:

    - Load Win2K SP2 for a fix. (I'm using SP3.)
    - Check the SMTP smarthost. (Mine is empty.)
    - Check the FQDN. (I've tried both the machine name and
    localhost, with the same results. The Check DNS button
    says both are fine.)
