Delivery to remote port 465 requires that you use stunnel.
Look with your favourite search engine for: postfix stunnel 465.
Delivery to port 465 is not built into the Postfix SMTP client
because that protocol has been obsolete for 10+ years. That said,
it would not take much code to support this in the SMTP client. I
guess it is not implemented for techo-religuous reasons.
