  • SBS 2003 Exchange SMTP issue

    Hello: Setup exchange to use smarthost for SMTP. If I setup the SMTP connector prompt Use the following smarthost for forward all mail for this connector and enter the smarthost name ie. smtp.mywebsite.com, the mail remains in the queue and eventually NDR. If I enter the IP address instead, tghe connector wors fine. I can however ping and telnet the name and it resolves correctly. Have it working but would like to know what the issue is. Thanks.

    Is your internal domain the same as your public domain, or do you have a zone for the public domain in your internal DNS? If the IP address works then it is not a connection issue, it must be a name resolution issue.

      Thanks for replying. Not real versed in SBS 2003 or Exchange 2003. Sort of inherited the Administrator position. We have an internal domain ourcompany.local and external domain ourcompany.com. Is that what you mean? Could you please provide more detail on what and where I should look for the solution. My solution is working but I realize there is a root cause of the problem somewhere. Whould like to resolve the root issue. Thanks

        I suspect that it is a name resolution issue - nothing to do with Exchange.
        You need to see whether the name that you are entering as the smart host resolves correctly - to the correct external IP address.
