Unable to send to, and others using SBS2003 Exchange

Currently email etc is hosted on webmail, we want to be able to leave the hosting on the web but download and send using the local SBS2003 Exchange, I've configured the POP3 Connector to download emails from the webmail site, however SMTP will not send to some domains. The most frequent ones are and however there are others periodically. Currently all they do is sit in the queue in scheduled status sometimes for days. If I go into the Server Management> Advanced Mangement> First Organization (Exchange)> Servers>Server2k3> Queues I can see:

SmallBusiness SMTP Connector - (SMTP Connector) listed as scheduled without another "Time next connection retry"

Same for and any others that do not send. If I manually "Force connection" The messages will send.

    How is the SBS Connector configured? To use DNS or to use a smart host?

    Check your DNS is working correctly using this question:

    Ensure that DNS is configured externally using the guide on my web site:

    You may end up having to switch the SMTP Connector to use a smart host instead, which will be your ISPs SMTP Server.
