Hello Michael,

You're right to sense a possible problem.  Plain ol' forwarding adds
headers for your domain, which isn't good because you want bogofilter to
see the headers of the original message.  On the other hand, if the
messages are forwarded as attachments you can get good results.  What
you want is a script that will extract the original message so it can
then be used for training.  In bogofilter's contrib directory
are two perl scripts:  mime.get.rfc822 and bfproxy.  Give them a
test and see if they're what you need.  If not, feel free to
cut/paste/enhance.

HTH,

David
