I'm having sudden second thoughts about how I should be dealing with mails that get qualified incorrectly and dropped into the wrong mailbox.
I've operated for years on the understanding that if, e.g., a mail gets dropped in spam (or unsure) that SHOULD have been sent to my inbox, the fix is to manually move it from the spam (or unsure) box into my inbox. I do this in mutt by selecting the misqualified mail and saving it to the desired box (which removes it from where it had been put).
but I've been reading stuff on the spambayes web site and don't find any reference to doing it that way. In fact most of the discussion seems to be how to do it in outlook or other non-Linux system.
I no longer use SpamBayes for my personal mail, but still (from time-to-time) update the training database on mail.python.org. For that, I use the train-to-exhaustion tool (contrib/tte.py in the SpamBayes repo). You said nothing about how asymmetric your ham and spam databases are, or how big either one is, so I'm not sure what properties your current database has. In general, I do try to keep them reasonably small and current. I just got a new computer and can't currently login to mail.python.org, but when I do, I have a further shell script wrapper around tte.py I can send your way, and refresh my brain about the steps necessary to update things.
