4.3 安装配置Spamassassin
在新的AMaVisd-new已经结合了Spamassassin功能，所以只要用 ports安装了 AMaVisd-new，那Spamassassin 也已经安装好了。
添加需要的用户
mail# pw useradd spam -c "Spam Bayes Learner" -d /var/empty -s /sbin/nologin

mail# pw useradd notspam -c "Not Spam Bayes Learner" -d /var/empty -s /sbin/nologin
      
修改/usr/local/etc/mail/spamassassin/local.cf
use_bayes 1
bayes_path /var/amavis/.spamassassin/bayes
auto_learn 1
auto_learn_threshold_nonspam -2
auto_learn_threshold_spam 15
修改/usr/local/etc/amavisdcf在mydoman&nbs;&bp;''''toping.net'''';一段下面增加
$max_requests&nbssp;= 10;
$child_timeout=5*60;
 
@bypass_virus_checks_acl = qw( . );
@local_domains_acl = ( ".$mydomain" );
 
$final_spam_destiny = D_PASS;
 
read_hs\witelist_sender,&nsp;'''var/amavis/whitelist'''');
read_hs\backlist_sender,&nsp;'''var/amavis/blacklist'''');
rahs(\%spam_lovers,&nbs;'''vr/amavis/spam_lovers'''');
建立所需要的文件
mail# touch /var/amavis/whitelist
mail# touch /var/amavis/blacklist

mail# touch /var/amavis/spam_lovers
mail# chown vscan /var/amavis/whitelist
mail# chown vscan /var/amavis/blacklist
mail# chown vscan /var/amavis/spam_lovers
mail# echo spam@toping.net >> /var/amavis/spam_lovers

mail# echo notspam@toping.ne >> /var/amavis/spam_lovers
      
修改/usr/local/etc/postfix/main.cf，添加
content_filter = smtp-amavis:[127.0.0.1]:10024

建立自动学习体系
mail# vi /usr/local/sbin/my-sa-learn.sh
      
#!/bin/sh
if [ -e /var/mail/spam ]; then
/usr/local/bin/sa-learn --spam -p /var/amavis/.spamassassin/user_prefs --mbox /var/mail/spam
 
rm /var/mail/spam > /dev/null
fi
 
if [ -e /var/mail/notspam ]; then
/usr/local/bin/sa-learn --ham -p /var/amavis/.spamassassin/user_prefs --mbox /var/mail/notspam
 
rm /va/mail/notspam > /dev/null
fi     
mail# chmod a+x /usr/local/sbin/my-sa-learn.sh
建立学习知识库：
mail# /usr/local/bin/sa-learn --sync -p /var/amavis/.spamassassin/user_prefs
      
加入自动运行校?
mail# crontab -e
      
5 0 * * * /usr/local/sbin/my-sa-learn.sh
