In normal operation that is exactly what TMDA does -- re-injects the
message via sendmail to the original envelope recipient, from the
original envelope sender.

I think I'm going to have to go through the archives and try to get
some context on what the original problem was.  I'll get back to you
on this.

No, it's not.  It offers an SMTP proxy daemon, tmda-ofmipd, that
mail-clients can connect to in order to send mail.  The client has to
be configured to use SMTP-AUTH.  However, I don't believe you're using
that right now, and you may not have any need to.  tmda-filter
operates at delivery time, after the MTA has received and queued the
message and is now attempting to deliver it.  It typically (for
Postfix) runs from a user's dot-forward file.
