以下是具体安装步骤:
一.PHP(FastCGI)环境
一.PHP(FastCGI)环境
   1.MySQL安装
@版本：mysql-5.0.41.tar.gz
   安装过程：
……………………………安装开始………………………………………………
# groupadd mysql
# useradd -g mysql mysql
#./configure --prefix=/usr/local/mysql --with-extra-charsets=gb2312,gbk
--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
--with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static
--sysconfdir=/etc --enable-assembler
# make && make install
# scripts/mysql_install_db --user=mysql     //数据库安装
# bin/mysqld_safe --user=mysql &   //起动mysqld
…………………………安装结束……………………………………………
echo "/usr/local/mysql/lib/mysql">> /etc/ld.so.conf //postfix编译里会用到
基本操作：
1.     起动/关闭MySQL
/usr/local/mysql/bin/mysqld_safe &
/usr/local/mysql/bin/mysqladmin -u root –p shutdown
2.     设置密码
mysqladmin -u root password 'new-password'

二.邮件发送接收相关包的安装

再继续安装前先清理一下系统自带的一些软件

Sendmail相关包rpm –q sendmail

sendmail-8.13.8-2.el5

----------------------------------------------

清除：

rpm -e sendmail --nodeps

Sasl 相关包列出 rpm -qa|grep sasl

cyrus-sasl-2.1.22-4

cyrus-sasl-devel-2.1.22-4

cyrus-sasl-plain-2.1.22-4

cyrus-sasl-lib-2.1.22-4

---------------------------------------------

清除：

rpm -e --nodeps cyrus-sasl cyrus-sasl-devel cyrus-sasl-plain cyrus-sasl-lib
然后是创建以下用户及组

用户名	组名	作用	备注
mysql	mysql	数据库mysql运行用户	以上已创建
vmail	vmail	nginx 服务运行用户	以上已创建
vmail	vmail	Postfix虚拟邮件帐号所使用的用户及组	uid,gid:1001,1001
postfix	Postfix	Postfix主程序使用的帐号和组	Uid,gid:1000,1000
	Postdrop	Postfix setgid_group	setgid_group=postdrop 1002
amavis	amavis	邮件扫描
clamav	Clamav	病毒扫描

ln -s /usr/src/kernels/2.6.18-128.el5-i686 /usr/src/linux //避免以下安装编译出现问题

一．安装courier-authlib

安装过程：

……………………………安装开始………………………………………………

Shell> tar jxvf courier-authlib-0.62.2.tar.bz2

Shell> cd courier-authlib-0.62.2

Shell>./configure

--with-mailuser=vmail --with-mailgroup=vmail

--with-mysql-libs=/usr/local/mysql/lib/mysql

--with-mysql-includes=/usr/local/mysql/include/mysql

--prefix=/usr/local/authlib

--without-stdheaderdir

Shell> make && make install

Shell> make install-configure

…………………………安装结束……………………………………………

---------------------------------------------------------

一般情况下，anthlib的安装应该是容易完成的。

配置：

配置authlib.在目录/usr/local/authlib/etc/authlib中，修改文件authdaemonrc及authmysqlrc。

vim /usr/local/authlib/etc/authlib/authdaemonrc

vi /usr/local/authlib/etc/authlib/authdaemonrc
authmodulelist="authmysql"
authmodulelistorig="authmysql"
DEBUG_LOGIN=2

修改上面3项，其他的项保持不变。这个修改前2行表示用mysql认证模块；把DEBUG_LOGIN的值有默认的“0”改成“2”的用意是运行postfix时有更多的信息输出，通过生成的日志以帮助排错。

vi /usr/local/authlib/etc/authlib/authmysqlrc
MYSQL_SERVER localhost
MYSQL_USERNAME extmail
MYSQL_PASSWORD extmail

MYSQL_DATABASE extmail

MYSQL_SOCKET /usr/local/mysql/tmp/mysql.sock

MYSQL_PORT 3306
MYSQL_USER_TABLE mailbox
MYSQL_CRYPT_PWFIELD password //这里需要注意
#MYSQL_CLEAR_PWFIELD password

DEFAULT_DOMAIN mail.test.com
MYSQL_UID_FIELD ‘1001’
MYSQL_GID_FIELD ‘1001’

MYSQL_LOGIN_FIELD username
MYSQL_HOME_FIELD '/var/mailbox/'

MYSQL_NAME_FIELD name
MYSQL_MAILDIR_FIELD maildir
MYSQL_QUOTA_FIELD concat(quota,'S')
MYSQL_WHERE_CLAUSE active='1'

特别注意MYSQL_UID_FIELD和MYSQL_GID_FIELD字段的值，这里是‘1001’,也可以是其它的，但一定要与vmail用户及组相一致（id vmail可以得出这2者的值）

后续工作还有，所以现在还不能测试。

-------------------------------------------------------

二．安装SASL

cyrus-sasl-2.1.22.tar.gz

安装过程：

……………………………安装开始………………………………………………

Shell> tar zxvf cyrus-sasl-2.1.22.tar.gz

Shell> cd cyrus-sasl-2.1.22

Shell> ./configure --disable-anon

--disable-gssapi //授权

--disable-sample

--disable-digest //授权

--enable-plain

--enable-login

--enable-sql

--with-mysql=/usr/local/mysql

--with-mysql-includes=/usr/local/mysql/include/mysql

--with-mysql-libs=/usr/local/mysql/lib/mysql

--with-authdaemond=/usr/local/authlib/var/spool/authdaemon/socket

Shell> make

Shell> make install

…………………………安装结束……………………………………………

配置：

ln -s /usr/local/lib/sasl2 /usr/lib/sasl2 //sasl的安装目录是/usr/local/lib/sasl //安装结束后有Warning警告

echo “/usr/local/lib” >> ld.so.conf //否则postfix 编译里会找不到libsasl2.so.2

创建文件 /usr/local/lib/sasl2/smtpd.conf,并加入如下内容：

pwcheck_method: authdaemond

mech_list: PLAIN LOGIN

log_level: 3

authdaemond_path: /usr/local/authlib/var/spool/authdaemon/socket

Sasl2需要使用文件/usr/local/authlib/var/spool/authdaemon/socket，但默认情况下，其属性是744，需要把它加上执行权限，以便文件属组（主）而外的其它用户可以执行。运行命令

chmod +x /usr/local/authlib/var/spool/authdaemon即可，如果不这样处理，smtp验证无一例外会失败的。

创建运行时需要的目录并调试启动
# mkdir -pv /var/state/saslauthd
# /usr/local/sbin/saslauthd -v //看看版本是不是2.1.22

saslauthd 2.1.22

authentication mechanisms: getpwent pam rimap shadow
# /usr/local/sbin/saslauthd -a shadow pam -d //正常不会报错

启动并测试
# /usr/local/sbin/saslauthd -a shadow pam
# /usr/local/sbin/testsaslauthd -u root -p password //正常显示0: OK "Success"成功

(Password改成机器登录账号root 的密码,这里不是账号不是指的MySQL账号密码。否则会提示：

0: NO "authentication failed",同时，注意这里测试不用开启authdaemond(authlib)

加入开机自启动

Echo “/usr/local/sbin/saslauthd -a shadow pam” >>/etc/rc.local

三．安装postfix

Make参数参考：安装源文件READ_FILES目录
# more README_FILES/MYSQL_README

安装过程：

……………………………安装开始………………………………………………

Shell> tar zxvf postfix-2.5.6.tar.gz

Shell> cd postfix-2.5.6

Shell> make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/local/include/sasl' 'AUXLIBS=-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm -L/usr/local/lib -lsasl2'

@@注意：1. 如果没有Makefile文件，需要设置成make -f Makefile.init

2. /usr/local/mysql/include 如果此目录下还有mysql目录，应改成/usr/local/mysql/include/mysql

3. /usr/local/mysql/lib 如果此目录下还有mysql目录，应改成/usr/local/mysql/lib/mysql

如果没有意外，make这一步很快就执行完了，接下来就是安装，使用的命令是

Shell> make install

程序先自动执行一阵子，然后会进入交互状态，等待用户的输入，一般情况下，一路回车即可完成所有的安装。

最后:
生成别名二进制文件，这个步骤如果忽略，会造成postfix效率极低：
shell> /usr/bin/newaliases

…………………………安装结束……………………………………………

检验postfix是否支持sasl认证，如果输出为以下结果，则支持：
shell> /usr/sbin/postconf -a //postfix 安装没有指定目录

cyrus
dovecot

shell> /usr/sbin/postconf -m |grep mysql

mysql //没有的话需重新编译postfix

四．安装imap

Postfix只是实现邮件系统的smtp功能，pop3或imap则需要另外的软件来实现，这个软件就是courier-imap(当然也有别的软件可以选择)。

……………………………安装开始………………………………………………

Shell> tar jxvf courier-imap-4.4.1.tar.bz2

Shell> cd courier-imap-4.4.1

Shell>./configure

--prefix=/usr/local/imap

--with-RedHat

--disable-root-check

--enable-unicode=utf-8,iso-8859-1,gb2312,gbk,gb18030

--with-trashquota

--with-dirsync

--with-mysql-libs=/usr/local/mysql/lib/mysql --with-mysql-includes=/usr/local/mysql/include/mysql

--with-authmysql

--with-authmysql=yes

CPPFLAGS='-I/usr/local/authlib/include' LDFLAGS='-L/usr/local/authlib/lib/courier-authlib'

COURIERAUTHCONFIG='/usr/local/authlib/bin/courierauthconfig'

[以上时间长一些]

Shell> make

Shell> make install

Shell> make install-configure

……………………………安装结束………………………………………………

配置：

……………………………配置开始………………………………………………

修改配置文件/usr/local/imap/etc/pop3d及/usr/local/imap/etc/imapd。把/usr/local/imap

/etc/pop3d 文件的行“POP3DSTART=NO”改成“POP3DSTART=YES”，再依照这个形式把文件/usr/local/imap/etc/imapd的行“IMAPDSTART=NO”改成“IMAPDSTART=YES”即可。

加入开机启动：

cp courier-imap.sysvinit /etc/rc.d/init.d/imapd // courier-imap.sysvinit在安装源文件中

chmod +x /etc/rc.d/init.d/imapd

chkconfig --add imapd

[chkconfig --level 2345 imapd on]

Service imapd start //输出Starting Courier-IMAP server: imap pop3

检测：

netstat -tnl|egrep "110|143"

五．安装pcre

安装前先卸载系统自带的pcre-6.6-1.1

Rpm –e pcre

自带的pcre RPM包可能与一些有冲突，可以先卸载掉

Shell> rpm –e pcre如果提示libpcre.so.0与别的软件有依存关系。可以这样

先备份一下libpcre.so.0这个文件，然后。

Shell> rpm -e pcre –nodeps

……………………………安装开始………………………………………………

Shell> tar zxvf pcre-7.8.tar.gz

Shell> cd pcre-7.8

Shell> ./configure

Install prefix .................. : /usr/local

C preprocessor .................. : gcc -E

C compiler ...................... : gcc

C++ preprocessor ................ : g++ -E

Link pcregrep with libz ......... : no

Link pcregrep with libbz2 ....... : no

Link pcretest with libreadline .. : no

Shell> make

Shell> make install

……………………………安装结束………………………………………………

六．安装maildrop

注意%源码安装的，将courierauthconfig 命令链接到/usr/bin里，假设装在：
/usr/local/authlib/bin/courierauthconfig，则：
ln -s /usr/local/authlib/bin/courierauthconfig /usr/bin/courierauthconfig
这样编译出来的maildrop才会Courier Authentication Library extension enabled.

……………………………安装开始………………………………………………

Shell> tar jxvf maildrop-2.0.4.tar.bz2

Shell> cd maildrop-2.0.4

Shell>./configure

--enable-sendmail=/usr/sbin/sendmail

--enable-trusted-users='root vmail'

--enable-syslog=1

--enable-maildirquota

--enable-maildrop-uid=1001

--enable-maildrop-gid=1001

--with-trashquota

--with-dirsync

Shell> make

Shell> make install

Shell> cp /usr/local/bin/maildrop /usr/bin //可有可无

……………………………安装结束………………………………………………

验证安装是否成功:

Shell> maildrop –v

[root@localhost postfix]# /usr/local/bin/maildrop -v

GDBM extensions enabled.

Courier Authentication Library extension enabled. //这行重要,没有的话要查一下原因

Maildir quota extension enabled.

This program is distributed under the terms of the GNU General Public

License. See COPYING for additional information.

FAQ:

如果没有显示Courier Authentication Library extension enabled.说明你的maidrop还不支持courier auth，请仔细检查，重新编译maildrop建议不要自定义目录安装，可以减少不必要的麻烦，删除很方便：直接在已经编译的源代码目录 make uninstall 就行

知道maildrop把邮件移动到哪个用户目录还是非常有必要的，这个操作就是maildrop的日志记录。这里我们创建一个新文件/etc/maildroprc，这个文件就2行内容：如果加入反SPAM,需要更改以下内容

[root@mail mailbox]# more /etc/maildroprc

logfile "/var/log/maildrop.log"

to "$HOME/$DEFAULT"

Shell> touch /var/log/maildrop.log

Shell> chown vmail.vmail /var/log/maildrop.log
shell> chown vmail.vmail /var/mailbox

三.Webmail相关包安装

一．安装webmail

安装前先安装Unix-Syslog-1.1.tar.gz

http://search.cpan.org/CPAN/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz

Tar zxvf Unix-Syslog-1.1.tar.gz

cd Unix-Syslog-1.1

perl Makefile.PL

make

make install

安装：DBI-1.605.tar.gz(先安装)

DBD-mysql-4.010.tar.gz

安装extmail

……………………………安装开始………………………………………………

Shell> Mkdir -p /var/www/extsuite/extmail

将下载的extmail-1.0.4.tar.gz解压到 /var/www/extsuite/extmail下

Shell> cd /var/www/extsuite/extmail/

Shell> cp webmail.cf.default webmail.cf

[Shell> chown –R vmail.vmail /var/www/extsuite/extmail]

[shell> chmod +x /var/www/extsuite/extmail/cgi]

……………………………安装结束………………………………………………

2.extmail cgi脚本配置

   #MAXFORK=5
   MAXFORK=20
   #MAXREQS=100
   MAXREQS=500
   #TIMEOUT=120
   TIMEOUT=300
   PORT=12009 #端口号与nginx.conf文件保持一致,
   SU_UID=vmail
   SU_GID=vmail

安装extman

……………………………安装开始………………………………………………

Shell> mv extman-0.2.3 /var/www/extsuite/extman

//Shell> chown -R vmail:vmail /var/www/extsuite/extman

创建extman运行时所需要临时目录

Shell> mkdir -pv /tmp/extman

Shell> chown -R vmail.vmail /tmp/extman

初始化数据库时，请更改init.sql中extmail.org的名称为自已域名

Shell> cd /var/www/extsuite/extman/docs/

//Shell> vi init.sql

将extmail.org 全部替换为mail.test.com(自己根据自己的域名替换)

修改cgi目录的属主：
# chown -R vmail.vmail /var/www/extsuite/extman/cgi/

Shell> mysql -u root -p < ./extmail.sql

Shell> mysql –u root –p < ./init.sql

Extmail 和 extman 详细配置

1. extmail 配置 vi webmail.cf

SYS_USER_LANG = en_US 改为SYS_USER_LANG = zh_CN

SYS_MAILDIR_BASE = /home/domains 右边改为 /var/mailbox

SYS_MYSQL_USER = db_user 右边改为extmail

SYS_MYSQL_PASS = db_pass 右边改为extmail

SYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sock 右边改为/usr/local/mysql/tmp/mysql.sock

SYS_AUTHLIB_SOCKET = /usr/local/authlib/var/spool/authdaemon/socket

………………………

2. extman 配置 vi webman.cf

SYS_MAILDIR_BASE = /home/domains 右边改为/var/mailbox

SYS_DEFAULT_UID = 1001

SYS_DEFAULT_GID = 1001

SYS_MYSQL_SOCKET = /usr/local/mysql/tmp/mysql.sock

SYS_CAPTCHA_ON = 0 //关闭图形验证码

起动NGINX和extmail cgi

/var/www/extsuite/extmail/dispatch-init start
/usr/local/nginx/sbin/nginx

测试：

输入网址：http://mail.test.com/extmail/cgi/index.cgi

管理员账号root@mail.test.com extmail*123*

FAQ:

Can't open /tmp/extman//sid_e438c6f837880729ff491bd3f7ea3f01, No such file or directory

解决：mkdir -pv /tmp/extman

chown -R vmail.vmail /tmp/extman

apache 运行用户及组为vmail

二．安装webmail图形化日志

1. RRDTool安装

下载：http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.30.tar.gz

http://ftp.gnome.org/pub/gnome/sources/libart_lgpl/2.3/libart_lgpl-2.3.20.tar.gz(先安装)

步骤：

--------------------------------------------------------------------------------------------------
libart安装(包括了libart库文件,对平面图形的良好性能很有帮助)

# tar zxvf libart_lgpl-2.3.20.tar.gz && cd libart*

# ./configure --prefix=/usr/local/libart

# make && make install

RRDTool安装(Rrdtool 依赖libpng freetype libart库支持，安装这个前应先保证这几个库已安装上)
# tar zxvf rrdtool-1.2.30.tar.gz && cd rrd*

# more /doc/rrdbuild.txt (安装说明)

# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/libart/lib/pkgconfig
# pkg-config --libs freetype2(检测一下是否可以找到freetype2)
-L/usr/local/lib -lfreetype -lz

# ./configure --prefix=/usr/local/rrdtool //本机需要连网

# make && make install

2．安装File-Tail perl模块
下载：http://search.cpan.org/CPAN/authors/id/M/MG/MGRABNAR/File-Tail-0.99.3.tar.gz
基本步骤：
# tar zxvf File-Tail-0.99.3.tar.gz && cd File*
# perl Makefile.PL
# make && make install
以下是安装信息：

cp Tail.pm blib/lib/File/Tail.pm

Appending installation info to /usr/lib/perl5/5.8.8/i386-linux-thread-multi/perllocal.pod

３．启动图形日志服务测试

Shell> cp -r /var/www/extsuite/extman/addon/mailgraph_ext /usr/local/

其它设置：(因为rrdtool安装在非标准目录，所以其perl模块找不到,拷备到标准目录即可)
cp -r /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/* /usr/lib/perl5/5.8.8/i386-linux-thread-multi/

shell> /usr/local/mailgraph_ext/mailgraph-init start

shell> /usr/local/mailgraph_ext/qmonitor-init start

加入到开机启动:

Shell> echo “/usr/local/mailgraph_ext/mailgraph-init start”>>/etc/rc.local

Echo > echo “/usr/local/mailgraph_ext/qmonitor-init start”>>/etc/rc.local

图形日志测试

添加为支持虚拟域和虚拟用户所用到的配置文件

1. 添加为支持虚拟域和虚拟用户所用到的配置文件

创建目录/etc/postfix/mysql,然后手动创建四个配置文件：mysql_virtual_alias_maps.cf，mysql_virtual_domains_maps.cf，mysql_virtual_mailbox_limit_maps.cf，mysql_virtual_mailbox_maps.cf。这4个文件的内容分别如下：

*也可以直接从extman解压包的docs目录下直接挎备以下几个文件*

Shell> mkdir –p /etc/postfix/mysql

Shell> more mysql_virtual_alias_maps.cf

user = extmail

password = extmail

hosts = localhost

dbname = extmail

table = alias

select_field = goto

where_field = address

additional_conditions = AND active = '1'

shell> more mysql_virtual_domains_maps.cf

user = extmail

password = extmail

hosts = localhost

dbname = extmail

table = domain

select_field = domain

where_field = domain

additional_conditions = AND active = '1'

shell> more mysql_virtual_mailbox_limit_maps.cf

user = extmail

password = extmail

hosts = localhost

dbname = extmail

table = mailbox

select_field = quota

where_field = username

additional_conditions = AND active = '1'

shell> more mysql_virtual_mailbox_maps.cf

user = extmail

password = extmail

hosts = localhost

dbname = extmail

table = mailbox

select_field = maildir

where_field = username

additional_conditions = AND active = '1'

2. webmail登录美化

登录界面美化：
在文件/var/www/extsuite/extmail/html/default/index.html 加入下面的标识，可以得到不同

<TR>

</TR>

邮件域的下拉列表，从而方便用户的使用。

在文件/var/www/extsuite/extman/html/default/index.html 加入下面的标识，可以得到不同

3. 认证发信测试

登录webmail,在mail.test.com域添加一用户test密码是123456

四.邮件反垃圾和反病毒

一．邮件反病毒和垃圾邮件过滤
1.反病毒

抗病毒使用软件是clamav

下载：http://jaist.dl.sourceforge.net/sourceforge/clamav/clamav-0.95.tar.gz

　安装：
#################################################################
# tar zxvf clamav-0.95.tar.gz &&cd clamav-0.95*
# useradd clamav
# ./configure --prefix=/usr/local/clamav

--with-dbdir=/usr/local/share/clamav //定义病毒数据库目录

# make && make install
################################################################
基本配置：
###################################################################
Clamav有2个配置文件，一个主配置文件/usr/local/clamav/etc/clamd.conf，一个病毒更新配置文件 /usr/local/clamav/etc/ freshclam.conf。现把修改好的配置文件列于下面：

[root@mail etc]# sed -e '/^#/d' -e '/^$/d' clamd.conf

LogFile /var/log/clamav/clamd.log

LogSyslog yes

LogVerbose yes

PidFile /var/run/clamav/clamd.pid

DatabaseDirectory /usr/local/share/clamav

LocalSocket /var/run/clamav/clamd.socket

StreamMaxLength 100M //附件大小,超过100M不扫描

User amavis

ScanMail yes

ScanArchive yes

[root@mail etc]# sed -e '/^#/d' -e '/^$/d' freshclam.conf

DatabaseDirectory /usr/local/share/clamav

UpdateLogFile /var/log/clamav/freshclam.log

LogVerbose yes

LogSyslog yes

PidFile /var/run/clamav/freshclam.pid

DatabaseOwner amavis

DatabaseMirror db.CN.clamav.net

DatabaseMirror database.clamav.net
##################################################################
这2个文件有很多注释，我用sed把它过滤掉了。Clamd.conf中，有"User amavis"这样一行。为什么不用默认的用户clamav而使用amavis呢？这样做的目的是为了与amavis-new结合在一起。既然没有这个用户，就手动创建一个（useradd amavis）。接下来需要手动创建一些目录并赋予相应的权限，用来记录日志等用途；我把它作成一个shell脚本，直接执行即可，脚本的内容如下所示：

######################################################

[root@mailserv2 ~]# more /root/clamav.sh

#!/bin/bash

# create directory for clamav
mkdir /usr/local/share/clamav
mkdir /var/log/clamav

chmod -R 744 /var/log/clamav

chown -R amavis:amavis /var/log/clamav

chown -R amavis.amavis /usr/local/share/clamav

mkdir /var/run/clamav

chmod 700 /var/run/clamav

chown amavis.amavis /var/run/clamav

#####################################################

# /usr/local/clamav/bin/freshclam 手动更新病毒库。

2.反垃圾
下载：http://www.ijs.si/software/amavisd/amavisd-new-2.6.2.tar.gz

安装：
#################################################################
通过脚本一步到位：注意目录及版本

[root@mail virus]# vi /usr/local/bin/amavis.sh

#!/bin/bash

cd /usr/local/src/virus

tar zxvf amavisd-new-2.6.2.tar.gz && cd amavisd*

mkdir -p /var/amavis /var/amavis/tmp /var/amavis/var /var/amavis/db

chown -R amavis:amavis /var/amavis

chmod -R 750 /var/amavis

cp amavisd /usr/local/sbin/

chown root /usr/local/sbin/amavisd

chmod 755 /usr/local/sbin/amavisd

cp amavisd.conf /etc/

chown root /etc/amavisd.conf

chmod 644 /etc/amavisd.conf

mkdir /var/virusmails

chown amavis:amavis /var/virusmails

chmod 750 /var/virusmails
################################################################
执行完脚本后别忘记检查一下是否都按我们的意愿工作，如/usr/local/sbin目录是否有文件amavisd。

Amavisd的配置文件/etc/amavisd.conf比较复杂，需要修改的内容如下：

$max_servers=8;
$daemon_user = 'amavis';
$daemon_group = 'amavis';
$mydomain = 'mail.test.com';
$db_home = "$MYHOME/db";
$inet_socket_port = 10024;
$sa_tag_level_deflt = 5.0;
$sa_tag2_level_deflt = 6.2;
$sa_kill_level_deflt = $sa_tag2_level_deflt;
$virus_admin = "virusalert@$mydomain";
$sa_spam_subject_tag = '***SPAM*** ';
$forward_method = 'smtp:127.0.0.1:10025';

$notify_method = $forward_method;
$final_virus_destiny = D_DISCARD;
$final_banned_destiny = D_DISCARD;
$final_spam_destiny = D_PASS;
['ClamAV-clamd',
&ask_daemon, ["CONTSCAN {}n", "/var/run/clamav/clamd"],
qr/bOK$/, qr/bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

上述修改确认无误后，执行 # /usr/local/sbin/amavisd debug 测试amavis。一般而言，测试皆不能正常进行，因为所需要的很多perl模块很可能没有被安装。还好，报错信息给出了所需的模块。这时你需要到www.cpan.org下载相关的模块，然后安装;也可能遇到包依赖，再下载依赖的包，安装这个依赖，再反回来安装先前那个包，如此反复，很是烦人，极考验人的耐性。等到/usr/local/sbin/amavisd debug 输出没有错误方才完成。有另外一种方法，即运行 [root@mailserv2 ~]# perl -MCPAN -e shell ，然后执行 cpan> install Time::HiRes 这样的命令挨个安装缺少的perl模块。根据我的经验，这样干很耗时，并且有的模块用这种方法安装还不灵，所以还不如在网站下载模块安装有效。

最终调试结果部分:

May 12 17:01:02.413 test.com /usr/local/sbin/amavisd[25969]: ANTI-VIRUS code loaded

May 12 17:01:02.413 test.com /usr/local/sbin/amavisd[25969]: ANTI-SPAM code loaded

May 12 17:01:02.414 test.com /usr/local/sbin/amavisd[25969]: ANTI-SPAM-SA code loaded

3. mail:: spamassassin配置如下

# more /etc/mail/spamassassin/local.cf
#####################################

required_hits 5

use_bayes 1

bayes_auto_learn 1

skip_rbl_checks 0

use_razor2 1

use_pyzor 0

#####################################
# chown –R amavis.amavis /usr/share/spamassassin
# chmod –R 777 /usr/share/spamassassin
以上两步不这样做,mail:: spamassassin配置文件不会起作用.

4.添加postfix反病毒和反垃圾
# more /etc/main.cf

content_filter = smtp-amavis:[127.0.0.1]:10024

max_use = 10

# more /etc/postfix/master.cf

# antispam #

可能出现的问题:

Hits值总为0,可能是mail:: spamassassin没有起作用,查看一下/usr/share/spamassassin/是否有访问权限,其属主为amavis

6.病毒库和反垃圾规则更新
[root@MailSer1 ~]# crontab -l

0 0 1 * * root wget -N -P /usr/share/spamassassin www.ccert.edu.cn/spam/sa/Chinese_rules.cf;kill -HUP `cat /var/run/spamd.pid`

00 00 * * * /usr/local/clamav/bin/freshclam

补充：

垃圾邮件分捡：

# more /etc/maildroprc
logfile "/var/log/maildrop.log"
if (/^X-Spam-Flag:.*YES/)
{
    exception {
        to "$HOME/$DEFAULT/.Junk/."
    }
}

到此，整个邮件系统安装基本完成，在安装过程中，参考了网上很多资料，同时也发现了许多问题!这几篇文章难免还有一些不足，我会不断完善，也欢迎大家指正！
