    I've configured this same setup but with a different domain Host and it
    worked fine but I'm having problems getting this configured correctly and
    would appreciate some pointers.

    The system is a fresh install of SBS2k3 with ISA2k4, all patches and
    updates, with two nics. The domain AAAAAA.COM was purchased by the company
    and is hosted at Yahoo. I have it pointing to DynDNS. I have the server
    behind a Linksys Firewall that is connected to TimeWarner RoadRunner on a
    dynamic IP. The linksys has DDNS configured and connected to DynDNS and it is
    updating fine.

    The problem is that I can't seem to send email to some domains while most
    work fine. One domain is my own company web site and I know it is working
    fine because everyone else can access it fine.

    Anybody know if Yahoo domain name service has any issues or where I can start?

    Thankx, David.

    PS: the client doesn't want to pay the money to have a static IP because
    they are useing the RR internet phone for their fax with free long distance.

    Do you get a bounce back of
    "There was a SMTP communication problem with the recipient's email server.
    Please contact your system administrator."

    If so, you may have to use SmartHost instead of DNS for Mail Delivery..

    Run CEICW
    Server Managment >> Internet and E-mail >>Connect to the internet

    In the Send mail Section Instead of DNS use Host.
    And use your IPS's SMTP Gateway...
    Example: smtp.comcast.net

    This will send mail through the ISP's SMTP gateway and the other host will
    see it as a "Legit" mail server instead of a spammer..
