You may need to fake the Message-ID header to get around Exchange
duplicate message protection (if you use Exchange), otherwise the
original (technically resent) message will be discarded. I insert the
sha1 hash of the df-file there.

H??Message-ID: <353001cbee50$f9913ab0$a10ea8c0 at home>


H??Message-ID: <sha1 hash here at home>

I have a script for easy handling of this.
