I use SquirrelMail and seperate out my missed spam email to a "Train/SPAM" folder and the wrongly tagged ones to "Train/HAM" folder and automate the process of training SpamAssassin via a daily cron.
Put the "SAtrain.sh" file in "/etc/cron.daily" directory.
#!/bin/bash # SAtrain.sh # Trains SpamAssassin with Spam and Ham mbox feeds... # Put this file in "/etc/cron.daily" directory. # chmod 700 "/etc/cron.daily/SAtrain.sh" echo "Training SpamAssassin Begin:" echo "Learning from Spam..." /usr/bin/sa-learn --spam --configpath=/etc/mail/spamassassin --showdots --mbox /home/user/mail/Train/Spam sleep 10 echo "Learning from Ham..." /usr/bin/sa-learn --ham --configpath=/etc/mail/spamassassin --showdots --mbox /home/user/mail/Train/Ham sleep 10 echo "Clearing Spam Feed..." cat /dev/null > /home/user/mail/Train/Spam echo "Clearning Ham Feed..." cat /dev/null > /home/user/mail/Train/Ham echo "Training SpamAssassin Completed!"
With spamassassin trained daily and my "required_hits set to 1.9" in my "~/.spamassassin/user_prefs" file, I have been able to get an accuracy of emails being tagged as spam for about 99.9% of my emails... Woohooo!!
