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
一、maildrop安装
tar zxvf maildrop-1.5.2.20030423.tar.gz
./configure [options]
make
make install-strip
make install-man
二、安装 perl-Time-HiRes-1.38-3.i386.rpm
rpm -ivh perl-Time-HiRes-1.38-3.i386.rpm
三、安装clamav-0.65.tar.gz
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。
四、安装qmail-scanner-1.20.tgz
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。
