587 is an authenticated port. Not sure you can connect interactively. I
could be wrong. If I am, where are the username and password for TLS
coming from?

I suspect it is connecting just fine at the TCP/IP level, but then the
exchange drops into the TLS negotiations and that where it's failing.

Also, I seem to recall that using Google for SMTP requires some sort of
setup at the Google end.

You may find it easier overall to use SES with an AWS instance. The
whole authentication thing falls away if you set up a suitable instance
policy.
