A change in ISP requires a new smart host for exchange 2003  which only accepts mail submitted over port 465 and requires authentication. I have seen a handful of ways to do this. Via programs and exchange. Is there a best way. I am bit confused.

The settings are all configured on the SMTP Virtual Server.

You can specify Port 465 and the relevant credentials there, then configure your SMTP Connector with the Smarthost FQDN or IP address in square brackets.

Shout if you need more specific details.

Restart the SMTP service after making the changes to force them to be active.

I have changed the outbound security and applied the credentials, I have changed the port outgoing to 465 and changed the smarthost to the FQDN required. Do I need to change the port under properties>general>advanced from port 25tcp to 465 ?

Just to be more specific,

I went and modified the FQDN to that of the new smtp smarthost in the SMTP connector. I then in the SMTP Virtual server went to properties>delivery>outbound security and changed it to the appropriate authentication. I then clicked on outbound connections and changed the port to 465. I restarted the SMTP service and had no luck. There is no outbound firewall either traffic should travel via port 465.

Can you telnet to the smarthost using port 465 e.g.,

telnet mail.smarthost.com 465

Did you restart the Simple Mail Transfer Protocol Service to force the new settings into effect?

I have not tried to telnet to the smarthost. I have gone back to the configuration that they previously had. I am looking at potentially running stunnel to get the outbound smtp to connect to the host.
