currently, JBCS does not clean up after itself, when a message is deleted, it is only removed from messagedata table, it is recommended, for now, to have a cron job, that cleans the other tables, there is code(sql) in forums that does this, or if you like, I can post what I am doing... nice, so it sounds like it is working fine for you now, messagedata, should have message headers in it, if, and only if, the message has not been deleted by the mail client. so nothing wrong with your driver, it is "natural" for this to happen. I suck at hibernnate, and trying to learn(not trying very hard), so cant help with blobs vs. long blobs, one of the other guys, may be able to help! Glad you got it working!
