Hi Toby,

The inbound part (pop3proxy, hammie, the Outlook stuff, whatever) could
cache the messages, then the SMTP proxy could compare the forwarded
messages with the cache (somehow - there'd be no Message-Id to compare) to
find the original to train against.

You're right - losing headers will make a difference, even with the fairly
minimal header tokenising we currently do.  When I added the Unsure
classification to pop3proxy, I tested it by forwarding a bunch of spams to
myself and they all came out Unsure where they had been Yes before - at
first I thought it was a bug, but then a couple of genuine spams rolled in
and were classified correctly.
