建设qmail服务器的病毒防护系统

1、 maildrop-1.5.2.20030423.tar.gz
2、perl-Time-HiRes-1.38-3.i386.rpm
3、clamav-0.65.tar.gz
4、qmail-scanner-1.20.tgz

tar zxvf maildrop-1.5.2.20030423.tar.gz
./configure [options]
   make
   make install-strip
   make install-man

grouadd clamav
useradd –g clamav –s /bin/false clamav
tar zxvf clamav-0.65.tar.gz
cd clamav-0.65
./configure
make check
make install
更新病毒库，freshclam
把freshclam加入crontab 定时更新病毒库，
修改/usr/local/etc/clamav.conf
Example前加# 或删掉
执行clamscan 测试
执行clamd
然后执行clamdscan

groupadd qscand
useradd –g qscand –s /bin/false qscand
tar zxvf  qmail-scanner-1.20.tgz
cd qmail-scanner-1.20
./configure --qmail-queue-binary /var /qmail/bin/qmail-queue
 --admin postmaster \
--domain abc.com.cn --notify sender,admin --local-domains
abc.com.cn --lang en_GB\
 --debug yes --unzip yes --scanners clamscan

检查有无错误
然后安装./configure --qmail-queue-binary
/var /qmail/bin/qmail-queue  --admin postmaster \
--domain abc.com.cn --notify sender,admin
--local-domains abc.com.cn --lang en_GB\
--debug yes --unzip yes --scanners clamscan --install

看看是否在/var/qmail/bin/qmail-scanner-queue.pl是否存在
chown qscand:qscand /var/qmail/bin/qmail-scanner-queue.pl
chmod 4755 /var/qmail/bin/qmail-scanner-queue.pl
然后用一个普通用户登陆，执行/var/qmail/bin/qmail-scanner-queue.pl -z
如果没有Can't do setuid出现，恭喜你，
如果有回到安装文件目录，有个contrib目录，
make
make install

附加步骤：chown qscand:qscand /var/qmail/bin/qmail-scanner-queue
chmod 4755 /var/qmail/bin/qmail-scanner-queue
chmod 0755 /var/qmail/bin/qmail-scanner-queue.pl

然后用一个普通用户登陆，执行/var/qmail/bin/qmail-scanner-queue -z
/var/qmail/bin/qmail-scanner-queue –g
修改环境变量
1 在你的qmail启动脚本加入
QMAILQUEUE=/var/qmail/bin/qmail-scanner-queue.pl如果作了附加步骤用下面的
QMAILQUEUE=/var/qmail/bin/qmail-scanner-queue
export QMAILQUEUE
2还有一种方法：请参考FAQ.php
Instead set it under the tcpserver smtp rules file (you're using Qmail -
so you already know what that is - right? :-). That way you can even setup
Qmail-Scanner to only scan mail from particular SMTP client IP address ranges/etc.
This is now the only officially supported mechanism. Set it something like this:
#/etc/tcpserver/smtp.rules
#
# No Qmail-Scanner at all for mail from 127.0.0.1
127.:allow,RELAYCLIENT="",RBLSMTPD="",
QMAILQUEUE="/var/qmail/bin/qmail-queue"
# Use Qmail-Scanner without SpamAssassin on any mail from the local network
# [it triggers SpamAssassin via the presence of the RELAYCLIENT var]
10.:allow,RELAYCLIENT="",RBLSMTPD="",
QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl"
#
# Use Qmail-Scanner with SpamAssassin on any mail from the rest of the world
:allow,QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl"
Then run "maketcprules" or something like "tcprules /etc/tcp.smtp.cdb
 /etc/tcp.smtp.tmp < /etc/tcp.smtp" to rebuild the database

重起qmail 测试，这里有测试程序
/youdir/software/qmail-scanner-1.20 test_installation.sh

不知什么原因，我的clamscan 扫描不到病毒，经过测试，发现了原因，正确解决方法：

修改qmail-scanner-queue.pl中的
my $clamscan_options="-r --disable-summary
  --max-recursion=10 --max-space=1000000";为
my $clamscan_options="-r --mbox --disable-summary
  --max-recursion=10 --max-space=1000000";
就可以ＯＫ了
