安装amavisd-new
yum install amavisd-new
中文过滤规则
cp Chinese_rules.cf
/usr/share/spamassassin/
service amavisd
start
lsof -i:10024
安装ClamAV
yum install clamd
vim /etc/clamd.conf
注释掉 80行 ‘TCPSocket 3310’，我们将使用unix
socket而不是TCP，两者不可并存
设置相关目录权限：
将clamav加到amavis运行组里，并调整目录权限，否则clamav将无法扫描amavisd-new产生的临时文件
usermod -G amavis
clamav
chown
amavis.amavis /var/spool/vscan
chmod 750 /var/spool/vscan
chown amavis.amavis
/var/spool/vscan/tmp
chmod 750 /var/spool/vscan/tmp
启动ClamAV及更新病毒库
service
clamd start
配置amavisd.con文件
vim /etc/amavisd/amavisd.conf
21 $mydomain =
‘server.com‘；
153
$myhostname = ‘mail.server.com‘；
54 @local_domains_maps = qw(.);
//对所有的域检查
修改投递/拦截的方法:
158
$final_virus_destiny = D_REJECT;
160 $final_spam_destiny =
D_REJECT; //邮件不会被投递给收件人，但会通知发件人邮件被拒绝
99 $sa_tag2_level_deflt =
19.2; 超过这个分数，允许在邮件标题加入[SPAM] 标记
100 $sa_kill_level_deflt =
19.9; 超过这个分数，直接將信件备份后删除
配置Amavisd与Clamav结合
在
“);
@av_scanners_backup = (”
上面添加

配置Amavisd与spam结合
14 @bypass_spam_checks_maps =
(\%bypass_spam_checks,\@bypass_spam_checks_acl,\$bypass_spam_checks_re);
配置Postfix 集成amavisd-new
修改/etc/postfix/master.cf添加如下：smtp-amavis unix -

-o lmtp_data_done_timeout=1200
-o lmtp_send_xforward_command=yes
-o disable_dns_lookups=yes
127.0.0.1:10025 inet

-o
mynetworks=127.0.0.0/8
修改 vim /etc/postfix/main.cf文件
content_filter=smtp-amavis:[127.0.0.1]:10024
重启postfix：
