That's where I was going.
I would use a custom post that looked for some header, and if found, would
move the outgoing email to some directory.
A cronjob would for f in SOMEDIR/`date +something`/*; do post <$f; done.

Yes, I knew how it worked.
We don't offer any way to respond, and I'd like to be able to optionally
respond :-)

If you mis-address an email, then you get an email back from postmaster
saying so.  The problem is that there are also lots of spammer who forge
origin addresses, and so for years (decades...) 99% of email from postmaster
is spam backscatter, and one tends to skip it.

I want to re-associate the bounce back to the message I sent, particularly if
it's one that I marked for "reliable" email.

That would be a clear user-level NAK, which means I need to figure out what 
Otherwise, I'm just waiting wondering why the other person hasn't answered
yet.  And I for instance, sometimes take a month to answer an important, but
not urgent query.
