一、防垃圾邮件及防病毒软件安装的介绍
一般来说，从广域网传到我们的服务器上的邮件，经过服务器的postfix 直接传给用户，并不做任何处理。这样会使我们的服务器很不安全，我们的邮件系统成了公用的邮件引擎。
现在我们利用 Amavisd-new（内容过滤）引擎 来做防病毒及防垃圾邮件处理。
过程说明：
广域网发过来的邮件同样会交给postfix 引擎处理，但是我们配置了Amavisd-new 内容过滤引擎，邮件会按照箭头指向流动，Amavisd-new首先会把邮件交给clamd 处理，clamd会检查邮件及其附录内容是否包含病毒，如果检查有病毒，clamd会把邮件放到一个病毒目录下面，并且向病毒邮件管理员(virusalert@mediawoz.cn)发信，说：您收到一份病毒邮件,同时把病毒邮件放到/var/virusmails/。如果邮件没有病毒，clamd会重新把邮件发给Amavisd-new过滤器；Amavisd-new过滤器再把邮件交由spamd 处理，spamd会检查邮件是否为垃圾邮件，这里有N种对垃圾邮件的处理方式，在spmad 里有配置。配置spmad会详细介绍。如果不是垃圾邮件，spamd 会再次把邮件发给Amavisd-new，此时Amavisd-new会把过滤的结果传给postfix，在经过postfix交给用户。
下面我们开始配置。
二、postfix的配置
因为postfix会把邮件交由Amavisd-new处理。所以我们要在/etc/postfix/main.cf里做相应的修改。在上次配置好的main.cf 中添加两行
[iyunv@mail postfix]# vi/etc/postfix/main.cf
#======================= content filter=====================
soft_bounce=yes
content_filter =smtp-amavis:[127.0.0.1]:10024
添加下面的文件内容
[iyunv@mail postfix]# vi/etc/postfix/master.cf

# of the file, see the master(5) manual page (command: "man 5master").

三、clamd 的配置
1、所需要的软件包
视频：http://www.boobooke.com/v/bbk1106/
下载地址
http://www.rpmfind.net/linux/rpm2html/search.php?query=clamav-db // clamav-db
http://www.rpmfind.net/linux/rpm2html/search.php?query=clamd // clamd
http://fr2.rpmfind.net/linux/rpm2html/search.php?query=clamav // clamav
[iyunv@mail postfix]# ls –l
-rw-r--r-- 1 root root 2763940 Feb 4 14:29 clamav-0.95.3-1.el4.rf.i386.rpm
-rw-r--r-- 1 root root 23781899 Feb 4 14:38 clamav-db-0.95.3-1.el4.rf.i386.rpm
-rw-r--r-- 1 root root 209763 Feb 4 14:21 clamd-0.95.3-1.el4.rf.i386.rpm
[iyunv@mail postfix]# rpm -iclamav-0.95.3-1.el4.rf.i386.rpm
[iyunv@mail postfix]# rpm -iclamav-db-0.95.3-1.el4.rf.i386.rpm
[iyunv@mail postfix]# rpm -iclamd-0.95.3-1.el4.rf.i386.rpm
注：在配置clamd之前要确保你的电脑能上网，需要配置你的网管，DNS。否则病毒库不能更新。
确保机器能上网之后，我们来配置clamd相关文件
主要配置文件为/etc/clamd.conf
[iyunv@mail etc]# cd /etc/
[iyunv@mail etc]# vi clamd.conf
这个文件里的内容一般不做修改，我们只要默认就够用了，下面我介绍几个参数，以便以后增强病毒过滤时做修改
ScanOLE2 //打开OFFICE文档扫描
ScanMail //打开邮件扫描
ScanArchive //扫描压缩包
ArchiveMaxFileSize 10M 最大扫描压缩包为10M，大于10M不扫描
ArchiveMaxRecursion 8 扫描压缩包8层，只扫描1~8层。8层以上的文件内容不扫描
ArchiveMaxFiles 1000 最多扫描压缩包内1000个文件
[iyunv@mail etc]# cd /etc/cron.daily/
[iyunv@mail cron.daily]# ls
00-logwatch 00-makewhatis.cron 0anacron freshclam hichina logrotate prelink rpm slocate.cron tmpwatch yum.cron
[iyunv@mail cron.daily]# sh -x freshclam //更新病毒库
在/etc 下面有很多cron的目录
[iyunv@mail etc]# ls cron*
cron.deny crontab
cron.d:
cron.daily:
00-logwatch 00-makewhatis.cron 0anacron freshclam hichina logrotate prelink rpm slocate.cron tmpwatch yum.cron
cron.hourly:
hichina
cron.monthly:
0anacron
cron.weekly:
00-makewhatis.cron 0anacron yum.cron
[iyunv@mail etc]#
如果把freshclam这个脚本放到不同的目录下面，就会不同的时间去更新病毒库。
如：放到cron.monthly下面，就每个月更新一次。默认在cron.daily下面。
病毒更新的日志会在 /var/log/clamav/freshclam.log
[iyunv@mail etc]# chkconfig clamd on // 开机自启动
[iyunv@mail etc]# /etc/init.d/clamd start
[iyunv@mail etc]# vi /var/log/clamav/clamd.log //查看clamd日志
四、splamd 配置
视频：http://www.boobooke.com/v/bbk1108/
下载地址http://dag.wieers.com/rpm/packages/
我们的服务器为 REL4 所以要求软件包
[iyunv@mail ~]# ll
spamassassin-3.1.8-1.el4.rf.i386.rpm
[iyunv@mail postfix]# vi/etc/mail/spamassassin/local.cf
# These values can be overridden by editing~/.spamassassin/user_prefs.cf
# (see spamassassin(1) for details)
# These should be safe assumptions and allowfor simple visual sifting

[iyunv@mail postfix]# vi/etc/mail/spamassassin/v310.pre
找到
# TextCat - language guesser
#
#loadpluginMail::SpamAssassin::Plugin::TextCat
去掉注释
# TextCat - language guesser
#
loadpluginMail::SpamAssassin::Plugin::TextCat
//上面是为了匹配local.cf的 ok_languages zh en 一行，否则报错
[iyunv@mail postfix]# chkconfig spamassassinon
[iyunv@mail ~]# /etc/init.d/spamassassin start
Starting spamd: [ OK ]
[iyunv@mail ~]# vi /var/log/maillog //spamd 日志目录
[iyunv@mail ~]# netstat –antp
tcp 0 0 127.0.0.1:783 0.0.0.0:* LISTEN 20707/spamd.pid
显示spamd程序成功运行
在网上下载一份Chinese_rules.cf
http://www.ccert.edu.cn/spam/sa/Chinese_rules.cf
这份文件是国内对汉字垃圾邮件判定的一些规则，默认安装的时候都是对英文进行判定，我们在 local.cf 中添加了ok_languages zh en 这一行，所以spamd会检查中文的邮件是否为垃圾邮件。这个邮件每周更新一次，所以我们还要在 crond.weekly目录下添加更新脚本。
[iyunv@mail ~]# cp Chinese_rules.cf /usr/share/spamassassin/
[iyunv@mail ~]# cd /etc/cron.weekly/
[iyunv@mail cron.weekly]# vi Chinese_rules.sh
#!/bin/bash
/usr/bin/wget -N -P /usr/share/spamassassinwww.ccert.edu.cn/spam/sa/Chinese_rules.cf
/etc/rc.d/init.d/spamassassin restart
[iyunv@mail cron.weekly]# chmod 755Chinese_rules.sh
至此spamd垃圾过滤程序完成。
五、amavisd 配置
1、 这个程序需要很多软件包，下面是软件包下载的地址
http://dag.wieers.com/rpm/packages/
确定你的系统里有如下软件包
首先是系统光盘应该有的，装系统时自带的软件包，我们服务器没装，所以我自己手动安装。
如果没有可以去上面那个网站去下载
我自己后安装的软件包有：
[iyunv@mail perl-deflat]# ll
perl-Archive-Tar-1.38-1.el4.rf.noarch.rpm
perl-BSD-Resource-1.2901-1.el4.rf.i386.rpm
perl-Class-Classgen-classgen-3.03-1.el4.rf.noarch.rpm
perl-Compress-Raw-Zlib-2.008-1.el4.rf.i386.rpm
perl-DBD-mysql-4.006-1.el4.rf.i386.rpm //这三个软件包只装一个就行，我没安装 perl-DBD-mysql-4.010-1.el4.rf.i386.rpm // 与数据库版本相关，不好修改。
perl-DBD-MySQL-4.013-2.fc12.i686.rpm
perl-Digest-HMAC-1.01-1.rhel2.1.dag.noarch.rpm //也是版本问题，我装的rhel2
perl-digest-hmac-1.01-66587cl.i386.rpm
perl-Digest-SHA1-2.11-4.el4.pp.i386.rpm
perl-IO-Compress-Base-2.008-1.el4.rf.noarch.rpm
perl-IO-Compress-Zlib-2.008-1.el4.rf.noarch.rpm
perl-IO-Socket-INET6-2.54-1.el4.rf.noarch.rpm
perl-IO-Socket-SSL-1.13-1.el4.rf.noarch.rpm
perl-IO-Zlib-1.09-1.el4.rf.noarch.rpm
perl-Net-DNS-0.63-1.el4.rf.i386.rpm
perl-Net-IP-1.25-1.el4.rf.noarch.rpm
perl-Net-SSLeay-1.32-1.el4.rf.i386.rpm
perl-Socket6-0.20-1.el4.rf.i386.rpm
perl-String-CRC32-1.4-1.el4.rf.i386.rpm
perl-TimeDate-1.16-1.2.el4.rf.noarch.rpm
注：我装包是遇到很多麻烦，比如版本不对，或者安装一个包会有很多依赖关系。
（1）装perl-digest-hmac-1.01-66587cl.i386.rpm的时候
[iyunv@mailperl-deflat]# rpm -i perl-digest-hmac-1.01-66587cl.i386.rpm
error:Failed dependencies:
perl-base = 3:5.8.5 is neededby perl-digest-hmac-1.01-66587cl.i386
所以我用perl-Digest-HMAC-1.01-1.rhel2.1.dag.noarch.rpm来替换
（2）perl-DBD-mysql-4.006-1.el4.rf.i386.rpm 这个软件包至今还没解决，它要求依赖
libmysqlclient.so.14 的依赖，但是我们的mysql 版本是5.1.30 是libmysqlclient.so.16
数据库不能换，里面有很多重要的东西。所以暂时我先放下。
2、安装好以上这些软件包之后先安装perl-File-Temp-0.20-1.el4.rf.noarch.rpm
[iyunv@mail amavisd]# rpm -i --nodocsperl-File-Temp-0.20-1.el4.rf.noarch.rpm
3、安装好这些系统里应该安装的之后。我们还要安装amavisd依赖的一些perl软件包
[iyunv@mail perl]# ls
perl-Archive-Zip-1.23-1.el4.rf.noarch.rpm
perl-BerkeleyDB-0.33-1.el4.rf.i386.rpm
perl-Convert-BinHex-1.119-2.2.el4.rf.noarch.rpm
perl-Convert-TNEF-0.17-3.2.el4.rf.noarch.rpm
perl-Convert-UUlib-1.051-1.2.el4.rf.i386.rpm
perl-IO-stringy-2.110-1.2.el4.rf.noarch.rpm
perl-MailTools-2.02-1.el4.rf.noarch.rpm
perl-MIME-tools-5.425-1.el4.rf.noarch.rpm
perl-Net-Server-0.97-1.el4.rf.noarch.rpm
perl-Unix-Syslog-1.0-1.el4.rf.i386.rpm
[iyunv@mail perl]# rpm -i perl-*
4、安装其他压缩及解压缩软件包
[iyunv@mail amavisd]# rpm -iarc-5.21o-1.el4.rf.i386.rpm cabextract-1.2-1.el4.rf.i386.rpmfreeze-2.5-2.2.el4.rf.i386.rpm lha-1.14i-19.2.2.rf.src.rpmlzo-1.08-4.2.el4.rf.i386.rpm lzop-1.01-2.el4.rf.i386.rpmncompress-4.2.4-41.rhel4.i386.rpm nomarch-1.4-1.el4.rf.i386.rpmunarj-2.63-0.a.2.el4.rf.i386.rpm unrar-3.6.8-1.el4.rf.i386.rpmzoo-2.10-2.2.el4.rf.i386.rpm ripole-0.2.0-1.2.el4.rf.i386.rpm

一些warning先不用去管他
5、安装amavisd
[iyunv@mail amavisd]# rpm -i amavisd-new-2.5.4-1.el4.rf.i386.rpm
warning: amavisd-new-2.5.4-1.el4.rf.i386.rpm:V3 DSA signature: NOKEY, key ID 6b8d79e6
[iyunv@mail amavisd]#
6、配置amavisd
Amavisd的文档目录
root@mail amavisd]# cd /usr/share/doc/amavisd-new-2.5.4/
[iyunv@mail amavisd-new-2.5.4]#ls
AAAREADME.first images README.contributed README.exim_v4 README.old.scanners README.sendmail RELEASE_NOTES
amavisd.conf LDAP.schema README.courier README.exim_v4_app README.performance README.sendmail-dual screen.css
amavisd.conf-default LICENSE README.courier-old README.exim_v4_app2 README.policy-on-notifications README.sendmail-dual.old test-messages
amavisd.conf.orig MANIFEST README.customize README.ldap README.postfix README.sql TODO-SNMP-AGENT
amavisd.conf-sample README.banned README.exim_v3 README.lookups README.postfix.html README.sql-mysql
amavisd-new-docs.html README.chroot README.exim_v3_app README.milter README.protocol README.sql-pg
[iyunv@mail amavisd-new-2.5.4]#vi amavisd.conf-sample
这个文档里有amavisd的详细说明，各个参数的使用都可以找到。
下面我们来配置amavisd
直接改下面的配置文件没有关系，/usr/share/doc/amavisd-new-2.5.4/ 下面有备份
[iyunv@mail amavisd-new-2.5.4]#cd /etc/
[iyunv@mail etc]# vi amavisd.conf
注意以下几个地方，其余地方可以按默认配置
$mydomain = 'mediawoz.cn'; # 改成我们自己的邮件域
$max_servers = 2;
#此处的2 要与/etc/postfix/master.cf 文件里
#smtp-amavis unix - - n - 2 smtpd
#相对应，改一处，则另一处也要修改。
@local_domains_maps= ( [".$mydomain"] );
# 注意，现在我们就一个邮件域，以后要多个邮件域则要把你所有的域名添加到这里。
$final_spam_destiny = D_PASS;
#对垃圾邮件的处理方式
#D_PASS不做任何处理，直接送给收件人
#D_DISCARD直接扔掉，不传送给发件人及收件人
#D_REJECT不传给收件人。发件人会收到拒绝传送的信息
#D_BOUNCE #不传送给收件人，也不给发件人。除了定义在$viruses_that_fake_sender_re
#病毒名称外的信件人，amavisd-new会传送DSN讯息给发件人。
$sa_auto_whitelist= 1; # 打开发件人白名单，如果发件人在白名单里，怎不认为
#是垃圾邮件
$sa_mail_body_size_limit = 200*1024; #超过特定大小的邮件不经过spmad扫描
### 配置垃圾邮件的分值 ###
$sa_tag_level_deflt = 4.0; # 超过这个分数者，才视为垃圾邮件打分数
# 加入X-Spam-Status及X-Spam-Level 信息
$sa_tag2_level_deflt= 18.5; # 超过这个分数者，才允许在邮件标题加入spam信息加入#x-Spam-Flag:YES及改写主题
$sa_kill_level_deflt= 10; # 超过这个分数者，肯定是垃圾邮件了，备份后删除邮件，并发
# 信给垃圾邮件管理员
$sa_dsn_cutoff_level = 9; # 超过这个分数者，将不会发出DSN信息
$sa_spam_subject_tag = '***SPAM*** '; # 在已判定是垃圾邮件标题上加上标记
read_hash(/%whitelist_sender,'/var/amavis/whitelist');
read_hash(/%blacklist_sender,'/var/amavis/blacklist');
找到
['ClamAV-clamd',
/&ask_daemon, ["CONTSCAN {}/n", "/var/run/clamav/clamd.sock"],
qr//bOK$/, qr//bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
把前面的数据去掉，注意红字部分，找到你系统里对应的clamd.sock
[iyunv@mail ~]# touch /var/amavis/whitelist
[iyunv@mail ~]# touch /var/amavis/blacklist
[iyunv@mail ~]# chown amavis:amavis/var/amavis/whitelist
[iyunv@mail ~]# chown amavis:amavis/var/amavis/blacklist
注：登记在whitelist的邮件地址或域名均不会被spamd打分为垃圾邮件
登记在blacklist的邮件地址或域名均会被spamd 视为垃圾邮件
写法每行一个邮件地址或域名
Test@test.com.cn
*@boss.com
修改了这两个文件之后，执行/etc/init.d/amavisd reload 重新读取配置文件，否则不生效。

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
[iyunv@mail~]# gpasswd -a clamavamavis
[iyunv@mail~]# usermod -G amavisclamav
[iyunv@mail~]# chown amavis.amavis/var/spool/vscan
[iyunv@mail~]# chmod 750/var/spool/vscan
[iyunv@mail~]# chown amavis.amavis/var/spool/vscan/tmp
[iyunv@mail~]# chmod 750/var/spool/vscan/tmp
