My approach to this problem is that I make two copies of every mail;
one copy goes into an 'everything' folder, and the other copy gets
delivered into 'inbox' or 'newspam' as appropriate.  As I review spam
(or find it as false negatives), I move it into a 'spam' folder.

For training, ham = everything - spam - newspam.  Naming three folders
doesn't seem to be a big deal, whereas naming all the innumerable
folders that my inbox gets sorted into would be.

The code to do this is checked in under contrib as bulktrain.sh and
bulkgraph.py, and described in BULK.txt.

I just ignore everything more than 120 days old, personally... and
that's just to keep the database around 20 meg.  Tests show that it
hurts accuracy by less than 1%.  Of course, ignoring everything over
a week old hurts less than 5%...
