Spam Learning - sa-learn integration ?

We use for years now (3-4) ASSP Deluxe for spam fighting. It has issues of course, and problems rising from time to time, most of them with ssl support and discarded messages, restarts, failing from time to time etc. But it works. And one feature that works nicely is the learning of spam. Using e-mails and forward them to assp-notspam@domain.com or assp-white@domain.com or for spam assp-black@domain.com and assp-spam@domain.com But except that brilliant feature is mostly problematic and needs a lot of maintenance. And I am wondering (if I switch back to spamassassin), is there something similar to it? I saw sa-learn. Did someone make it work ? I was thinking of a solution to make a script to check spam folder and inbox folder. (cron) inbox for ham, spam for spam. And just to inform the users to DRAG n DROP mails to junk folder if they are junk or from junk to move them to inbox folder. (And maybe a second cron script to flush spam folder after 30-40-x days). Will something like this work ? Anyone tried something similar ? Or is there a cPanel solution to this ? What I am trying to achieve is to make users "train" their spam. With ASSP this is easy, with Spamassassin I don't know (yet). If something is not spam and end up in spam folder I need a solution for the end user to "train", move this mail to inbox, and whitelist it somehow. And vice versa for spam. Any ideas?
