Procmail 过滤mail病毒
一、安装procmail
1. 下载最新版 http://www.procmail.org
2. tar zxvf procmail
3. cd procmail-3.15.2
4. make install
(解除安装make deinstall)
5. make install-suid (增加安全性)
检查一下/etc/sendmail.cf是否已将procmail替换原来的mail.local
Mlocal, P=/usr/bin/procmail, F=lsDFMAw5:/|@qSPfhn9, S=10/30, R=20/40,
A=procmail -Y -a $h -d $u
二、设定procmail
vi /etc/procmailrc
MAILDIR=/var/mail
VERBOSE=off
PATH=/bin:/sbin:/usr/bin:/usr/sbin/:/usr/local/bin:/usr/local/sbin
LOGFILE=/var/log/procmail.log

/dev/null

Procmail范例
将所有收到主旨有test字符的信放入/var/mail/IN.test档案中。
:0 b
* ^Subject:.*test
IN.test

三、观察系统日志统计
mailstat -km procmail.log
- m 合并错误至同一行(会删除原记录,重新计算)
- l 增加统计平均每人邮件大小,(会删除原记录,重新计算)
- k 保持原来的log檔
- o 使用旧的统计数据文件
- t 没有总统计资料
