Noooooooooooo!!!!!!  Not silently discard!!!!

I don't know if I can bring myself to do that, occasionally we have
problems with false positives, so silently dropping mail would seriously
aggravate the issue.  People around here depend on the bounce messages.

Perhaps a better solution for me would be to to make filter_end accept
if any one user accepts it, then for the users that reject it, call
delete_recipient then email the sender an error message from mimedefang
sourced from a black hole account.  This would prevent me from
processing the message more than once and would also allow me much more
control over the bounce message where I would only quote the subject to
reduce bandwidth and render bounce back spam useless due to the missing
payload.

Thoughts?
