the exception states that there is an issue connecting to the endpoint. Can you share the telnet session (without user accounts/passwords) that shows you how send an email? Maybe the other side is dropping the connection after it has been created out of whatever reason.

telnet just checks if the TCP connection is working, but does not guarantee you that sending an email actually works. You should check for that as well!
