[Mimedefang] add_recipient

[Jason Englander]

I need to take any mail passing through a mail server running MD
addressed to a certain domain and send it to in at mail.foo.org and
take any mail coming from that domain through this server and send
it to out at mail.foo.org  This is working just fine with stream_by_domain
and add_recipient.  ...but I need the sender on the *@mail.foo.org copy of
the message to be changed to me/root/whatever, so the original sender
doesn't get an undeliverable warning if mail.foo.org is down.  Anyone
have any suggestions?

I have several ideas, but all of them look like a big mail loop.  ie.
push(@Recipients,'in at mail.foo.org') before stream_by_domain, with
something wrapped around that to make sure that wasn't already done...
