I saw something about auto_learn...

(It will be used to auto-train the Bayesian learner from mails that are
"definitely spam" or "definitely nonspam", but isn't fully implemented
yet.)

As long as this feature is 'in the works' , let me put in my 2 cents: what will the learner mark as 'definitely spam'?

This also leads me back to my original questions, will the all_spam_to and whitelist_from scores affect the auto-learner. Furthermore, will the RBL stuff be added to the learner?
The RBL and LARGE scores (eg +-100) should be ignored. They do not demark spam, rather an RBL or whitelist item. RBLs may be from open relays, and once the RBL (eg osirusoft.com) database is updated due to a mislisting or closure of an open relay, SpamAssassin should no longer flag emails from that relay.

So, back to my original question, in Version 2.43, is there anyway to limit how the auto-whitelist learns? Well, doesn't sound like it. Here is a Version 2.43 patch:
