Hi, getting above error. Configuring AD Self service plus 1st attempt.

On a standalone desktop connected to the same network.

Domain registration works, password can be reset/etc. When configuring SMTP Mail settings I am getting this error.

Connection security - none. Tested with my own email address/password, exchange. Port 25 example.mydomain.com

Telnet to port 25 works fine. Windows FW has been disabled, no other FW installed.

Please advise?

regards,

Raj
