bayes question (sa-learn)

Hi

The SpamAssassin Gateway receives emails from the internet, filters and
forwards them (both, Spam and Ham) to the internal MTA. Thus, my users have
their spam-quarantine inboxes on the internal MTA.
I'm thinking about implementing a function on the SpamAssassin Gateway to
have SA learn spam and ham mails feeded by my users either to the email
address spam@mydomain.com or to the address ham@mydomain.com. These email
boxes of course would reside on the SA Gateway. 
However, I fear SA learns that headers coming from my internal MTA could be
spam and so causing false results on real spam. 

What experiences have you made or how have you solved this ?
(e.g. by setting up an IMAPd on the spamgateway?)

Thanks in advance

Best regards,
Philipp

Exactly. Forwarding e-mail breaks the original information and has to be 
avoided.

You can configure an imapd wherever you want, there are many tools out 
there to fetch IMAP-mailboxes to a local maildir/mbox/anything, which 
can then be used by salearn.
I use cyrus and have to folders "spamreport" and "hamreport" which are 
shared amount myusers, which have write, but no read access.
Even if I ignored those folders, my users would just be happy to give 
feedback and contribute. ;-)
