I would recommend Maia Mailguard.
http://www.maiamailguard.com/
Basically it is an quarantine management user interface for spam and
virus. It also has ham cache. Maia stores all hams/spams in its database.
User can login Maia and specify final destiny of each ham/spam. You can
"rescue" false positive. You can also tell Maia false negative. All
confirmed hams/spams are used to train bayes filter and then removed
periodically (by cron job).
If you have many users and you want to minimize management effort, Maia
would help you.
Which way is the best to get (ham and/or spam) mail out of user
mailboxes from exchange to linux for further "sa-learning".
Maybe there exist some Howto - we didn't manage to find them yet.
I have been using Maia for more than two years. Previous version 0.9.5a
does have spam quarantine but doesn't have ham cache, so sa-leaning of
spam is possible but I had same problem to sa-learning. But 1.0.0
has ham cache; it requires a fairly amount of storage, though.
