smtpd_* is the wrong configuration option. It applies to Postfix acting
as server, while you want to configure Postfix being the client. So you
have to read through man 5 postconf for smtp_ (smtp_tls_*) options.

For what a howto when you can read the manpage for postconf? Even each
smarthost can be configured with different musts, so there can't be a
globally valid setup guide.
