No, because this only affects original (incoming) message, but i need to identify
original recipient, when looking at the reply.

Hm, that may work. So, to not break recipient threads i probably may also
rewrite back 'References' and 'In-Reply-To' in outgoing message copy, which goes
to original sender, but use my own versions in message copies, which i redirect
locally to other users of that "shared" mailbox.. Thanks, i'll try this.
