apt-get install spamassassin spamc
groupadd -g 5001 spamd
useradd -u 5001 -g spamd -s /sbin/nologin -d /var/lib/spamassassin spamd mkdir /var/lib/spamassassin

ENABLED=1
SAHOME="/var/lib/spamassassin/" OPTIONS="--create-prefs --max-children 5 --username spamd --helper-home-dir ${S$PIDFILE="${SAHOME}spamd.pid"

nano /etc/spamassassin/local.cf
作適當的修改設定

/etc/init.d/spamassassin restart

nano /etc/postfix/master.cf

smtp inet n - - - - smtpd
改為
smtp inet n - n - - smtpd -o content_filter$=spamassassin
若原本是在 chroot 模式則要記得保留，否則smtp驗證會失敗。
最後加上
spamassassin unix - n n - - pipe user=spamd argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}

/etc/init.d/postfix reload
