<EXT:PLAINTEXT_OK>
Hello,
I posted a couple of days ago concerning a requirement to perform header
rewriting using sendmail. I've poked around more, and found that the
problem may be slightly more straightforward.
Background: We have a firewall box, which receives all mail, and forwards
it to the proper host. This works fine - headers are preserved, messages
look fine. We have an encryption box, which received messages, encrypts
them, and resends them to our POP server. Confusing, yes, but this is what
we have to work with. The problem lies with the encryption box - the
encryption software package is calling sendmail to pass along the newly
encrypted message. Naturally, it sends the message using the userid it is
running under.
What I want to do is this: All boxes in the mail chain will check for the
existence of a special header which, if not present, will be created and
the contents of the current From: header copied to it. This will give us a
pre-encrypted copy of the original sender. When mail hits the POP server,
it will rewrite the From: header, copying the contents of our special
header back.
This would serve our needs, however, if there is a better way, I'm all eyes.
Cheers!
Jon
