Thanks Phil,

I use public folders for the local Exchange users, but some external servers
either don't use Exchange or won't allow IMAP access from the Internet.

Will the header mangling make the message unusable by sa-learn? These are
messages that MS has already seen. The purpose of sending them back are only
to fine tune the bayesian filter. I would have thought that bayes only cares
about tokens in the body, not so much the headers?

If you "send" these messages via MS Outlook the headers will be mangled and
will be useless for spamassassin training.

Drag and drop the messages into public folders on your exchange server and
get them via IMAP for spamassassin training.

I would like to implement a feedback feature where users can send false
negatives and positives to a set of mailboxes, say spam and nospam. These
would be scanned by sa-learn every hour on a cron job.

Of course it is far too easy for a spammer to submit their spam to
nospam at mailscanner so I want to restrict the IP addresses that can submit
mail to that box to the mail servers where my users are on.

The MailScanner.conf doesn't seem to offer an option for blocking messages
in a ruleset. The closest I have seen is to block encrypted and unencrypted
messages on the same ruleset.

Does this indeed block all messages? Is there perhaps an easier way to do
this in sendmail?
