Bravo! (Choice of exim, that is :)

Apart from the stuff Lewis listed, Reply-to also (apparently) breaks
email clients, and is generally frowned upon.

I'm not sure the fact that you, being a trusted user, were able to
rewrite critical email fields is somehow proof that you don't need to be
a trusted user to rewrite critical email fields in exim :) Trusted user
refers to the owner of the exim process, not the sender of the email.

>From the exim.conf on my machine:

--- begin
# If this option is set, then any process that is running as one of the
# listed users may pass a message to Exim and specify the sender's
# address using the "-f" command line option, without Exim's adding a
# "Sender" header.

trusted_users = mail:alexhu
--- end

I interpret this to mean, "only trusted users may spoof their email
address" (which is essentially what you're trying to do anyway ;). I'm
willing to be corrected on this matter: I'm not email expert by any
means, exim being the one MTA I can actually abide using (sendmail gets
on my ..wotsits ;). But, the above configuration works for me.
