SMTP virtual server drops connection to smart host after EHLO RRS feed

  • Question

  • I have an additional SMTP virtual server listening on port 587 with SSL enabled on an Exchange 2003 SP2 server. I have configured the outbound delivery to a smart host running Postfix. Users are able to use this virtual server and can send to local domain users. If they try to send to an external domain, it should pass through the smart host (Postfix) but it cuts off the connection after the EHLO command and I get this message in the Postfix log:

    lost connection after EHLO from <servername>

    The default SMTP virtual server (listening to port 25) has no problem connecting to the same smart host. I'm stumped and I don't know what to do now.
