Hi there,
I have MSE Small Business. Last night messages stopped being delivered. They are now in the queued mail. I have restarted server. I have then frozen all and forced connection on one to no avail.
Any help would be much appreciated.

    What is the status of SMTP Service?

    The messages are stuck in Which Queue?

    Is this Exchange 2000 or Exchange 2003?

    Do you see any errors in the application logs?

    Are the Mailbox Store and Public Folder store mounted?

    How do I check status of SMTP service? There is no SMTP service listed in the Services
    It is MSE 2003
    The queue is the QUEUES in the First Storage Group
    Yes both are mounted

    Outgoing SMTP messages remain in the outgoing queue, and you do not receive any NDRs on a server that is running Exchange Server 2003, Exchange 2000 Server, or Small Business Server 2003

    I get event ID's 4006 (Message delivery to the host '' failed while delivering to the remote domain  '' for the following reason: The remote server did not respond to a connection attempt. )
    and 4000 (Message delivery to the remote domain '' failed for the following reason: Unable to bind to the destination server in DNS.)
    and type 7004 (This is an SMTP protocol error log for virtual server ID 1, connection #1. The remote host "", responded to the SMTP command "rcpt" with "550 authentication required  ". The full command sent was "RCPT TO:<>  ".  This will probably cause the connection to fail).

    I have resolution after calling in a specialist - it transpires the ISP DNS was blocked to non-client access and we weren't client. DNS settings were updated both on server and also way down in the bowels of MSE (which captures DNS settings at installation).
