Sadly, it won't work, at least not with Postfix.  There's no way to
save the auth state accepted via SMTP so that it can later be used by
LMTP for authenticated posting.  To be honest, I'm skeptical that'll
ever be a feature because it would require changing the Postfix
internal queue file format, and a big catch with that is some feeling
of uneasiness about passing such credentials.  At least that was my
impression a couple of years ago.

If passing such credentials is really important to you, you may have
to use Sendmail.  It know Sendmail handles it.
