Spamassassin 可以加入不同的 rules，以更有效阻檔垃圾電郵，以下網站有很多現成的 rules 可以下載，把 rules 放到 /etc/mail/spamassassin 目錄下面，然後重新啟動 spamassassin 即可:

我自己是用以下幾個 rules，其中最後一個是針對中文 spam 而設:

然後重新啟動 Spamassassin，方法如下:

/etc/rc.d/init.d/spamassassin restart

Debian:
/etc/init.d/rc.spamd restart

FreeBSD:
/usr/local/etc/rc.d/spamd.sh restart
