A couple of notes: 1. You can dump the contents of the bayesian database: sa-learn --dump Among other things, that shows you how many messages you've fed to the learn function. 2. You can run sa-learn in debug mode with the -D option. ----- Original Message ----- From: "Gregory Nowak" <greg@xxxxxxxxxxxxxxxxxx> To: "Speakup is a screen review system for Linux." <speakup at braille.uwo.ca> Sent: Wednesday, January 20, 2010 2:35 PM Subject: Re: ot, spamassassin question > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > John and all, > > On Wed, Jan 20, 2010 at 11:12:07AM -0600, John G.
