[spambayes-dev] Integrating SpamBayes with a Mail.app plugin

It's pretty rare to be able to modify a message once it's already in the
mail client, whatever mail client you're using (without hacking into the
stored file(s)).

Just clean out the database occasionally (besides which, this takes almost
no space, and space is cheap).  sb_filter will move to using the messageinfo
database that the rest of SpamBayes uses at some point, FWIW.

What do you mean by "batch mode"?  What exactly are you wanting users to be
able to do?
