TLS with Exchange server

We setup tls on our domino server with a verisign certificate and configured tls to negotiated outbound ssl and enabled inbound on the server. Restart the smtp listener task

Domino server never receives the starttls command from the exchange server and also does not when doing telnet but routes the mail over port 25 non ssl

Tech support says the issue is on the exchage end

ANy ideas

Tech Support is correct when they tell you that the other server needs to initiate the STARTTLS conversation. Your server is listening for the request, but if it doesn’t come, it drops down to free text.

HTH.
