我选用的Linux版本是CentOS5.2（好像是最新的吧），在初期安装系统时，对于服务器所需的RPM包我基本都安装了，避免在实验中出现RPM依赖关系，这样不太好，呵呵~~~~基本配置如下：
IP地址是192.168.1.200，网关是192.168.1.1（我选用的是虚机，为了解析互联网地址，我把网关指向了这个IP）。主机名是mail.benet.com。
邮件服务器的概况是基于独立网域搭配虚拟账号
第一部分 配置DNS
1. 基本配置
[root@mail ~]# vi /etc/named.rfc1912.zones
zone "benet.com" IN {
type master;
file "benet.com.zone";
allow-update { none; };
};zone "1.168.192.in-addr.arpa" IN {
type master;
file "192.168.1.rev";
allow-update { none; };
};
#添加两个域的设置（正向和反向），没加提示的就保持原来的配置，后面一样第四部分 安装配置Extmail和Extman
哈哈~~~~终于轮到我自己研究的东西了，希望能让大家满意！！！！
1. 安装配置Extmail
[root@mail ~]# tar -zvxf extmail-1\[1\]\[1\].0.4.tar.gz
#这个包和下面的Extman包可以到网上下载
[root@mail ~]# mv extmail-1.0.4/ /var/www/cgi-bin/extmail
[root@mail ~]# cd /var/www/cgi-bin/extmail/
[root@mail extmail]# cp webmail.cf.default webmail.cf
[root@mail extmail]# vi webmail.cf
SYS_CONFIG = /var/www/extsuite/extmail/修改为SYS_CONFIG = /var/www/cgi-bin/extmail/SYS_LANGDIR = /var/www/extsuite/extmail/lang修改为SYS_LANGDIR = /var/www/cgi-bin/extmail/langSYS_TEMPLDIR = /var/www/extsuite/extmail/html修改为SYS_TEMPLDIR = /var/www/cgi-bin/extmail/htmlSYS_SESS_DIR = /tmp/修改为SYS_SESS_DIR = /tmp/extmail
#需要手工创建并赋予权限SYS_USER_LANG = en_US修改为SYS_USER_LANG = zh_CNSYS_USER_CHARSET = utf-8修改为SYS_USER_CHARSET = gb2312SYS_MAILDIR_BASE = /home/domains修改为SYS_MAILDIR_BASE = /var/spool/mail
#这个修改是为了和
Postfix和Dovecot一致SYS_MYSQL_USER = db_user修改为SYS_MYSQL_USER = extmailSYS_MYSQL_PASS = db_pass修改为SYS_MYSQL_PASS = extmailSYS_MYSQL_ATTR_NDQUOTA = netdiskquota修改为SYS_MYSQL_ATTR_NDQUOTA = quotaSYS_G_ABOOK_FILE_PATH = /var/www/extsuite/extmail/globabook.cf修改为SYS_G_ABOOK_FILE_PATH = /var/www/cgi-bin/extmail/globabook.cfSYS_G_ABOOK_FILE_CHARSET = utf-8修改为SYS_G_ABOOK_FILE_CHARSET = gb2312
#上面很多都修改了路径，原因是与等下需要配置的Apache服务想对应，因为看别人文档按照做时，连链接都打不开，所以我用我自己喜欢的配置路径来解决，所以要修改的地方很多
[root@mail extmail]# chown -R postfix:postfix cgi/
[root@mail extmail]# mkdir /tmp/extmail
[root@mail extmail]# chown -R postfix.postfix /tmp/extmail/
[root@mail perl]# rpm -ivh perl-Unix-Syslog-1.0-1.el5.rf.i386.rpm
#需要Perl-Unix-Syslog的支持，这个perl包和下面的需要安装的Perl包都可以到网上下载到，提示个地址给大家http://dag.wieers.com/rpm/packages/2. 安装配置Extman
[root@mail ~]# tar -zvxf extman-0\[1\]\[1\].2.4.tar.gz
[root@mail ~]# mv extman-0.2.4/ /var/www/cgi-bin/extman
[root@mail ~]# cd /var/www/cgi-bin/extman/
[root@mail extman]# vi webman.cf
SYS_CONFIG = /var/www/extsuite/extman/修改为SYS_CONFIG = /var/www/cgi-bin/extman/SYS_LANGDIR = /var/www/extsuite/extman/lang修改为SYS_LANGDIR = /var/www/cgi-bin/extman/langSYS_TEMPLDIR = /var/www/extsuite/extman/html修改为SYS_TEMPLDIR = /var/www/cgi-bin/extman/htmlSYS_MAILDIR_BASE = /home/domains修改为SYS_MAILDIR_BASE = /var/spool/mail添加SYS_LANG = zh_CN
SYS_CHARSET = gb2312SYS_MYSQL_USER = webman修改为SYS_MYSQL_USER = extmailSYS_MYSQL_PASS = webman修改为SYS_MYSQL_PASS = extmail[root@mail extman]# chown -R postfix.postfix cgi/
[root@mail extman]# mkdir /tmp/extman
[root@mail extman]# chown -R postfix.postfix /tmp/extman
[root@mail perl]# rpm -ivh perl-GD-2.35-1.el5.rf.i386.rpm第五部分 配置Apache
[root@mail ~]# vi /etc/httpd/conf/httpd.conf
User postfix
Group postfix
#非常非常重要，使之以用户Postfix来识别Suexec模块，我的理解！！之后会因为这个配置没有修改会出现权限问题，相当之郁闷
NameVirtualHost *:80
<VirtualHost *:80>
ServerName mail.benet.com
DocumentRoot /var/www/cgi-bin/
ScriptAlias /extmail/cgi/ /var/www/cgi-bin/extmail/cgi/
Alias /extmail/ /var/www/cgi-bin/extmail/html/
ScriptAlias /extman/cgi/ /var/www/cgi-bin/extman/cgi/
Alias /extman/ /var/www/cgi-bin/extman/html/
</VirtualHost>
[root@mail perl]# chkconfig httpd on
[root@mail perl]# /etc/rc.d/init.d/httpd start
访问http://192.168.1.200/extmail和http://192.168.1.200/extman，只要看到页面即可，因为没有配置MySQL,所以很多管理工作做不成~~~~~~第六部分 配置MySQL
[root@mail ~]# chkconfig mysqld on
[root@mail ~]# /etc/rc.d/init.d/mysqld start
#第一次启动会有初始化过程
[root@mail ~]# mysqladmin -u root password 123456
[root@mail ~]# mysql -u root -p
Enter password:
[root@mail ~]# mysql -u root -p < /var/www/cgi-bin/extman/docs/extmail.sql
Enter password:
[root@mail ~]# mysql -u root -p < /var/www/cgi-bin/extman/docs/init.sql
Enter password:
#上面就是把相关的数据库导入到MySQL里面
[root@mail ~]# /etc/rc.d/init.d/mysqld restart
[root@mail ~]# mysql -u extmail -p
#用命令show databases;来查看表是否导入，当然了，进入时的密码就是Extmail第七部分 测试
再次访问http://192.168.1.200/extman，进入管理界面，默认内置账号是root@extmail.org（不能修改），密码是extmail*123* 。（句号放开点）
我创建第一个域benet.com时，会提示“添加benet.com失败，原因：INSERT command denied to user 'extmail'@'localhost' for table 'domain'”，所以我们还要给extmail再MySQL中赋予权限
[root@mail ~]# mysql Cu root -p
mysql> grant all privileges on *.* to 'extmail'@'localhost' identified by 'extmail' with grant option;
#给的权限很大了~~~~~~
好了，再次添加域和用户，在进入http://192.168.1.200/extmail进行用户登陆收发邮件，当然，最开始提到是搭建独立网域搭配虚拟用户，所以可以创建benet.com相关的子域sales.benet.com等等，当然不用去修改DNS的配置！！！！ 好累，我写完了，如果大家喜欢，顶一下，这是给我最大的动力了！！！之后我会对邮件的安全的相关配置进行研究，力求大家都喜欢~~~~！！！！！[root@mail ~]# cd /var/named/chroot/var/named
[root@mail named]# vi benet.com.zone
$TTL 86400
@ IN SOA mail.benet.com. root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
@ IN NS mail.benet.com.
mail IN A 192.168.1.200
@ IN MX 5 mail.benet.com.[root@mail named]# vi 192.168.1.rev
$TTL 86400
@ IN SOA mail.benet.com. root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry

200 IN PTR mail.benet.com.[root@mail named]# vi /etc/resolv.conf
nameserver 127.0.0.1
[root@mail named]# chkconfig named on
[root@mail named]# /etc/rc.d/init.d/named start
2. 测试
使用命令nslookup和dig查看是否能够解析域名，也可以去解析互联网地址，但是我觉得意义不大，我没有注册域名服务，所以不能对公网提供服务，注意2点：一是需要设置网关才能解析，在上面已经提示；二是默认安装时没有caching-nameserver这个包，所以到安装光盘下查找到并安装。第二部分 安装配置Postfix
1. 安装配置Postfix
[root@mail ~]# rpm -ivh postfix-2.3.3-2.src.rpm
[root@mail ~]# cd /usr/src/redhat/SPECS/
[root@mail SPECS]# vi postfix.spec
%define MYSQL 0修改为%define MYSQL 1
#使其支持MySQL服务。这些配置方法和橡皮树老师中视频的所需的软件包一样，如果嫌麻烦，可以到论坛搜橡皮树老师的视频，而且提示了所需软件包
[root@mail SPECS]# rpmbuild -ba postfix.spec
#我用真机安装时时间很短，但是我用虚机编译了很长时间（大概15分钟），所以要有耐心，不要中途觉得编译不正确而停止，这样你会更痛苦
[root@mail SPECS]# cd /usr/src/redhat/RPMS/i386/
[root@mail i386]# rpm -ivh postfix-2.3.3-2.i386.rpm
[root@mail ~]# cd /etc/postfix/
[root@mail ~]# mv main.cf main.cf.bak
#将原来配置更换名字做个备份
[root@mail ~]# vi main.cf

#这个配置文档是拿橡皮树老师的用的，很多也不知道意思，我只了解一些基本的配置参数的意义，呵呵 下面是4个与MySQL相关的配置，与橡皮树老师不同的是我后面将导入的数据库名称是Extmail，所以这里要做调整，Dovecot的配置也是一样，怎么导入数据库将在后面写出来；
[root@mail postfix]# vi 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'[root@mail postfix]# vi mysql_virtual_domains_maps.cf
user = extmail
password = extmail
hosts = localhost
dbname = extmail
table = domain
select_field = description
where_field = domain
additional_conditions = AND active = '1'[root@mail postfix]# vi mysql_virtual_mailbox_limit_maps.cf

[root@mail postfix]# chkconfig sendmail off
[root@mail postfix]# /etc/rc.d/init.d/sendmail stop
#需把Sendmail服务停掉
[root@mail postfix]# /etc/rc.d/init.d/postfix start
好了，到此，Postfix的基本配置已经完成，如果启动成功就好了~~~~~第三部分 配置Dovecot

user_query = SELECT maildir, 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u'[root@mail postfix]# chkconfig dovecot on
[root@mail postfix]# /etc/rc.d/init.d/dovecot start
