  • Emails not arriving, SMTP comm incomplete

    Exchange 2003 SP2
    Windows 2003R2 fully patched
    Behind a ISA 2006 server


    Lately at a client some messages don't arrive. Checking the SMTP logs I notice that the communication seems incomplete. When I check the messages that don't arrive I notice that the DATA portion of the SMTP communication is missing. On succesful messages I see EHLO, MAIL, RCPT, DATA and QUIT. The messages that don't arrive are missing the DATA part. They look like this:

    EHLO host1.myisp.com
    MAIL [email protected]
    RCPT [email protected]
    QUIT host1.myisp.com
    EHLO host2.myisp.com
    MAIL [email protected]
    RCPT [email protected]
    QUIT host2.myisp.com

    No DATA part. Anybody seen this before? The server shows no errors. The messages don't show up in message trackng
