Unless you've redefined the behaviour, this is exactly correct; port
465 expects an SSL handshake before any other traffic. Plain telnet
won't do you much good unless you can do the SSL handshake by hand, and
then hand-encrypt/decrypt the outbound and inbound traffic. "openssl
s_client -connect" handles that SSL handshake and encrypt/decrypt
process, otherwise acting much like telnet.
Port 587 allows plaintext communication before enabling SSL with the
"STARTTLS" command.
