In Apple Mail (2.1 on OS X 10.4.7) I set up the SpamSieve rules as suggested for scoring spam and then seperating levels of spam - Blue, grey, purple, etc. on all messages and them moving the high scoring spam to the spam box. After which I have another rule that says "all mail with a to of firstname.lastname@example.org, move to mail box work". (So basicly, all mail heads towards my inbox and what ever is marked work goes to work inbox.)
The rules are set up in the order of scoring mail, coloring mail (and then deliver mail.
So far, the system has done a decent job of scoring and coloring mail. And mail has been able to handle seperating the reg inbox mail from the work mail. Spam Sieve has had trouble with completing its task of moving mail to the spam folder. It scores and colors them well, but it doesnt always move all the spam it has colored to the spam folder. Is there a time lapse between when it scores, and then colors and then moves the spam mail? Or is it done as the mail downloads? If its not a time lapse issue (ie-my not waiting long enough for the app to do its job) then how can I fix this?
