I am having a little trouble in getting sending mail from an SBS 2003 server out to the internet. I can receive but can't send. Can't seem to find the problem. I have a server with two nic cards and have tried to run the wizard several times. Any help would be appreciated.

    What type of service are you using? Many DSL and Cable internet providers do not allow you to send from a domain outside of their own. Try to relay through your providers SMTP servers. These setting are normally provided on their web site. Could be something like "" or "" as examples.

    Have you set your internal domain name to the same one that you have externally?
    ie have you set the internal dns to and you use on the internet?

    On your sbs server, do you have forwarders set to your ISP's dns servers in the forwarders tab in the dns manager?
    On the sbs server, are the dns entries on your NIC's set to use the sbs server itself for dns resolution?
