Yes, but when Postfix is a proxy, there is no "smarthost" involved, that
is what happens when Postfix is not a proxy. In proxy mode, all SMTP
transactions are proxied to a fixed downstream SMTP server which ultimately
accepts or rejects the message, but Postfix gets a chance to apply its
policy first.
