Rules Du Jour
There are many extra rules which can be used by Spamassassin to make MailScanner even more effective. One of the easiest ways to get hold of a good set of them is to use the RulesDuJour script
cd /usr/local/bin wget http://sandgnat.com/rdj/rules_du_jour chmod +x rules_du_jour mkdir /etc/rulesdujour edit /etc/rulesdujour/config
My file is shown below; make sure that the locations are correct for your system (and that it shows your email address!

rules_de_jour has a hard coded path to Bash which is wrong for FreeBSD - edit the file and change the first line so that it says:
#!/usr/local/bin/bash
Now run it to see if it works -
bash /usr/local/bin/rulesdujour
If all's well then you'll see it update and you'll get an email telling you what's happened. Finally, you need to add an entry to crontab so that the script runs once a day. You are asked to pick a random time to avoid overloading the servers
#update rules_du_jour at 19:58 each day 58 19 * * * root /usr/local/bin/rules_de_jour
(Thanks to Leif Neland for pointing out a mistake in that line)
