Don't do the inbox in the wee hours, any new messages you receive between 
the last to time you looked at your mail and the time the cron job runs will 
be learned as ham, even if it's spam. You'd need to undo that manually.

Also, be careful if you use imap. If you move/delete messages from a mailbox 
they remain until those changes are committed. When that actually happens 
depends on the mail client and how it's configured. So, there's a 
possibility that spam might remain in your inbox even after you've 
deleted/moved it.

(Don't forget to make sure sa-learn is on the path for cron).
