Does Postfix log the TLS handshake result?
If not, then I suspect that the client is not sending STARTTLS while
connected to the plaintext service on port 587, or that the client
is hanging while connected to the encrypted service on port 465,
waiting for the server's plaintext greeting.
Sorry, that is all the advice that I have as a non-Windows user.
