Exchange users can forward original mail, complete with headers if they
forward the original mail as an attachment. The easiest way to do this is
reduce the window size of Outlook and the new message window. Then simply
drag and drop the offending message(s) into the new message window and
send it on. Job done. The attached message retains it's headers and
original content.

The only challenge that I have not yet mastered is how to either merge 2
bayes databases (Not import from an old format) or allow two different
users to use the same database. When I changed the file group permissions
bayes learning stopped altogether (So I assume SA like to only have rw
user permissions only on the bayes files). I have a natty Postfix script
that will feed mail sent to a particular address to sa-learn
automatically. the problem is that Postfix is piping the mail to the
script and insists on doing so as any user except it's self (Or root, not
that I really want it doing so due to the security issues). The challenge
is that MS runs as Postfix user, the SA bayes files therefore are owned by
Postfix and only can have user rw permissions. Any ideas any one. My head
