Yes.  I implemented the idea discussed in
 http://thread.gmane.org/gmane.mail.spam.tmda.devel/5836

and it works pretty well for me, not only for auto-confirming, but also
to separate valid delivery notifications from those caused by mail with
forged envelopes.  See here for some documentation
 http://smarden.org/qconfirm/technical.html#outgoing
 http://smarden.org/qconfirm/technical.html#request
 http://smarden.org/qconfirm/qconfirm-inject.1.html
 http://smarden.org/qconfirm/qconfirm-notice.1.html

Ideally qconfirm should use some crypto instead of keeping track of
outgoing mail in a directory, so that you don't necessarily need to
inject mail on the mail server.

It handles qconfirm's requests, and optionally tmda's.  It doesn't for
qsecretary; if qsecretary would add a Message-ID as suggested above, it
would work automatically.
