SMTP is the most efficient mechanism for moving content out of the
Postfix queue. The only other option is to not queue the content
in Postfix at all, using qmail's SMTPs server as a "proxy filter",
that just happens to not re-inject mail back into Postfix.
You just have to make sure that any "ESMTP" features promised by
Postfix in its EHLO reply (DSN, ...) are understood by qmail, or
otherwise suppress them in Postfix. STARTTLS is an exception,
because Postfix terminates the TLS connection, and does not speak
TLS to the proxy filter.
