that's because it's configured for TLS on connect - which means you need
to be 'talking' TLS straight away.
(As opposed to 587, which requires a step up from plain SMTP to TLS with
"STARTTLS")
try using the openssl command line tool, with "openssl s_client -connect
<hostname>:465". Then you'll see the standard SMTP banner.
If you want to test 587, openssl s_client has a -starttls option that
makes it easy: but you need to also specify the protocol (try "openssl
s_client -starttls smtp -connect <hostname>:587"
