I'm running courier-imap on my box and have spamassassin move any spam into a spam folder (so I can make sure to check for false-positives). I have a cron job set to run sa-learn every night that trains ham from my legit mail folders and spam from the spam folder. This way, all I have to do if I get a false-negative is just move it to the spam folder and sa-learn will catch it that night. Using this technique, I've been able to keep my false-negative rate very low (I get about 5000 spam a month and only see about 10 spam in my inbox in a month, usually when I get more than 1 copy of a particular spam on the same day). I usually keep about 5000 messages in my spam folder and clear out the oldest. That way it's always fresh spam that's being considered. I could probably get away with fewer messages. I will note that I'm also running some optional modules like razor, pyzor, and dcc. Andrew "frugal" Dacey [EMAIL PROTECTED] http://www.tildefrugal.net/ -- [EMAIL PROTECTED] mailing list
