Re: Idea for improving the learning stage

Sounds like an interesting strategy on client-side filters which are 
integrated into the mail client, but I don't see how this could apply to 
a server-side filter.  Perhaps Bogofilter could be a link in the chain 
of such a system, but Bogofilter itself doesn't "watch" user behavior.
