This is my approach, stored in /etc/cron.hourly. It's very new, so I'm
still testing
it.
The goal is to learn HAM massages only if they are a day old, so that I can
manually
remove SPAM that slipped through. Mails tagged from Spamassassin are sorted
automatically into the "Junk.Spam" mailbox and learned after 12 hours. I
manually
move any missed SPAM into the .Junk mailbox, so I'm sure there are no
wrongly
tagged messages there, so I can learn those messages as soon as they are
found
by cron.
