Linux下架构基于虚拟用户、虚拟域的邮件系统（postfix）

实验配置概况图：

具体配置：

[root@gjp99 ~]# ifconfig

[root@mail etc]# chkconfig named on    开机自动启动！

postfix源代码支持mysql数据库！

配置：

1.安装所需的rpm包，这包括以下这些：

[root@mail etc]# yum install httpd  php  php-mysql  mysql  mysql-servenssl-devel  dovecot  perl-DBD-MySQL  tcl  tcl-devel  libart_lgpl  libaol-ltdl  libtool-ltdl-devel  expect

2、关闭sendmail，并将它的随系统自动启动功能关闭：
# service sendmail stop
# chkconfig sendmail off

3、安装以下开发所用到的rpm包组：

[root@mail etc]# yum grouplist  检查四个组是否启动
Development Libraries
Development Tools
Legacy Software Development
X Software Development

方法：
# yum groupinstall "packge_group_name"

4、启动mysql数据库，并给mysql的root用户设置密码：
# service mysqld start
# chkconfig mysqld on
# mysqladmin -u root password 'your_password'
也可以
---------------------------------授权本地用户
SET  PASSWORD FOR root@'localhost'=PASSWORD('redhat');
SET  PASSWORD FOR root@'127.0.0.1'=PASSWORD('redhat');
FLUSH PRIVILEGES;
-------------------------------授权远程用户
GRANT  ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'redhat';
FLUSH PRIVILEGES;

[root@mail etc]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

[root@mail ~]# vim /etc/postfix/main.cf
75 myhostname = mail.bht.com
82 mydomain = bht.com

98 myorigin = $mydomain      地址伪装使用

113 inet_interfaces = all

161 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

260 mynetworks =  127.0.0.0/8

[root@mail ~]# service postfix restart
Shutting down postfix:                                     [  OK  ]
Starting postfix:                                          [  OK  ]

说明:
myorigin参数用来指明发件人所在的域名；
mydestination参数指定postfix接收邮件时收件人的域名，即您的postfix系统要接收到哪个域名的邮件；
myhostname 参数指定运行postfix邮件系统的主机的主机名，默认情况下，其值被设定为本地机器名；
mydomain参数指定您的域名，默认情况下，postfix将myhostname的第一部分删除而作为mydomain的值；
mynetworks 参数指定你所在的网络的网络地址，postfix系统根据其值来区别用户是远程的还是本地的，如果是本地网络用户则允许其访问；
inet_interfaces 参数指定postfix系统监听的网络接口；

注意：
1、在postfix的配置文件中，参数行和注释行是不能处在同一行中的；
2、任何一个参数的值都不需要加引号，否则，引号将会被当作参数值的一部分来使用；
3、每修改参数及其值后执行 postfix reload 即可令其生效；但若修改了inet_interfaces，则需重新启动postfix；
4、如果一个参数的值有多个，可以将它们放在不同的行中，只需要在其后的每个行前多置一个空格即可；postfix会把第一个字符为空格或tab的文本行视为上一行的延续；

启动postfix
/usr/local/postfix/sbin/postfix  start

三、为postfix开启基于cyrus-sasl的认证功能

使用以下命令验正postfix是否支持cyrus风格的sasl认证，如果您的输出为以下结果，则是支持的：
 

[root@mail ~]# postconf -a
cyrus
dovecot
[root@mail ~]# vim /etc/postfix/main.cf

添加以下内容：
#################CYRUS-SASL############################
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_invalid_hostname,reject_non_fqdn_hostname,reject_unknown_sender_domain,reject_non_fqdn_sender,reject_non_fqdn_recipient,reject_unknown_recipient_domain,reject_unauth_pipelining,reject_unauth_destination

四、安装Courier authentication library

[root@mail ~]# tar -jxvf courier-authlib-0.63.1.20111230.tar.bz2 -C /usr/local/src

[root@mail ~]# cd /usr/local/src
[root@mail src]# ll
total 8
drwxrwxr-x 15 1000  1000 4096 Dec 31  2011 courier-authlib-0.63.1.20111230
drwxr-xr-x 16 1001 wheel 4096 Aug  3 18:37 postfix-2.8.2
[root@mail src]# cd courier-authlib-0.63.1.20111230/
[root@mail courier-authlib-0.63.1.20111230]# ls     看到有configure文件

执行以下命令：

./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --with-authmysql --with-mysql-libs=/usr/lib/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-ltdl-lib=/usr/lib --with-ltdl-include=/usr/include

make

make  install

[root@mail courier-authlib-0.63.1.20111230]# cd /usr/local/courier-authlib/var/spool/
[root@mail spool]# ll
total 4
drwxr-x--- 2 daemon daemon 4096 Sep 16 15:39 authdaemon
[root@mail spool]# chmod 755 authdaemon/

[root@mail spool]# cp /etc/authdaemonrc.dist  /etc/authdaemonrc
[root@mail spool]# cp /etc/authmysqlrc.dist   /etc/authmysqlrc

[root@mail spool]# vim /etc/authdaemonrc

27 authmodulelist=" authmysql"
34 authmodulelistorig="authmysql"

53 daemons=10

[root@mail spool]# vim /etc/authmysqlrc

MYSQL_SERVER localhost
MYSQL_USERNAME  extmail      (这时为后文要用的数据库的所有者的用户名)
MYSQL_PASSWORD extmail        (密码)

MYSQL_PORT 3306        (指定你的mysql监听的端口，这里使用默认的3306)
MYSQL_SOCKET  /var/lib/mysql/mysql.sock
MYSQL_DATABASE  extmail
MYSQL_USER_TABLE  mailbox
MYSQL_CRYPT_PWFIELD  password
MYSQL_UID_FIELD  '2525'
MYSQL_GID_FIELD  '2525'
MYSQL_LOGIN_FIELD  username
MYSQL_HOME_FIELD  concat('/var/mailbox/',homedir)
MYSQL_NAME_FIELD  name
MYSQL_MAILDIR_FIELD  concat('/var/mailbox/',maildir)

行号：(大概)26-28 49 56 68 83 92 113 119  128 133

注意：虚拟账号的主目录在  /var/mailbox

[root@mail courier-authlib-0.63.1.20111230]# pwd
/usr/local/src/courier-authlib-0.63.1.20111230
[root@mail courier-authlib-0.63.1.20111230]# ll |grep init
-rw-r--r-- 1 root root    943 Sep 16 15:37 courier-authlib.sysvinit
-rw-rw-r-- 1 1000 1000    892 May 25  2011 courier-authlib.sysvinit.in

# cp courier-authlib.sysvinit /etc/init.d/courier-authlib
# chmod 755 /etc/init.d/courier-authlib
# chkconfig --add courier-authlib
# chkconfig --level 2345 courier-authlib on

[root@mail ~]# echo "/usr/local/courier-authlib/lib/courier-authlib/"&gt;&gt;/etc/ld.so.conf.d/courier-authlib.conf
[root@mail ~]# ldconfig –v

[root@mail ~]# ldconfig -pv |grep courier

[root@mail ~]# service courier-authlib start(启动服务)
Starting Courier authentication services: authdaemond      courier-authlib的守护进程

新建虚拟用户邮箱所在的目录，并将其权限赋予postfix用户：
[root@mail ~]# mkdir -pv /var/mailbox
mkdir: created directory `/var/mailbox'
[root@mail ~]# chown -R postfix /var/mailbox
[root@mail ~]#  ll -d  /var/mailbox
drwxr-xr-x 2 postfix root 4096 Sep 16 16:22 /var/mailbox

接下来重新配置SMTP 认证，编辑 /usr/local/lib/sasl2/smtpd.conf ，确保其为以下内容：

[root@mail lib]# vim /usr/lib/sasl2/smtpd.conf
[root@mail lib]# cat /usr/lib/sasl2/smtpd.conf
pwcheck_methoeck_method: authdaemond
log_level: 3
mech_list:PLAIN LOGIN
authdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket:saslauthd

五、让postfix支持虚拟域和虚拟用户

1、编辑/etc/postfix/main.cf，添加如下内容：
##############Virtual Mailbox Settings########################
virtual_mailbox_base = /var/mailbox
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf

mailbox and try again later.
virtual_overquota_bounce = yes

2、使用extman源码目录下docs目录中的extmail.sql和init.sql建立数据库：

# tar zxvf  extman-1.1.tar.gz
# cd extman-1.1/docs
-------------------------------------------------------------------------------------------------------------
# mysql -u root -p <extmail.sql
# mysql -u root -p &lt;init.sql
   mysql -u root -p   进行验证
# cp mysql*  /etc/postfix/

 

[root@mail ~]# tar zxvf extman-1.1.tar.gz

[root@mail ~]# cd extman-1.1 /docs

[root@mail docs]# pwd
/root/extman-1.1/docs
[root@mail docs]# ls
backport                    ldap_virtual_domains_maps.cf   mysql_virtual_limit_maps.cf
extmail.schema              ldap_virtual_limit_maps.cf     mysql_virtual_mailbox_maps.cf
extmail.sql                 ldap_virtual_mailbox_maps.cf   mysql_virtual_sender_maps.cf
init.ldif                   ldap_virtual_sender_maps.cf    README.postfix
init.sql                    mysql_virtual_alias_maps.cf
ldap_virtual_alias_maps.cf  mysql_virtual_domains_maps.cf

[root@mail docs]# mysql -u root -p &lt;extmail.sql  
Enter password:  密码为：redhat
[root@mail docs]# mysql -u root -p &lt;init.sql
Enter password: 密码为：redhat
 

测试：

[root@mail docs]# mysql -u root -p
Enter password:  密码为：redhat

# cp mysql*  /etc/postfix/

3、授予用户extmail访问extmail数据库的权限
mysql&gt; GRANT all privileges on extmail.* TO extmail@localhost IDENTIFIED BY 'extmail';
mysql&gt; GRANT all privileges on extmail.* TO [email protected] IDENTIFIED BY 'extmail';
mysql&gt;FLUSH PRIVILEGES;   让设置的内容生效
cp mysql_virtual_* /etc/postfix/

service  postfix  restart

说明：启用虚拟域以后，需要取消中心域，即注释掉myhostname, mydestination, mydomain, myorigin几个指令；当然，你也

可以把mydestionation的值改为你自己需要的。

[root@mail docs]# service dovecot start
Starting Dovecot Imap:                                     [  OK  ]
[root@mail docs]# netstat -tupln |grep dov
tcp        0      0 :::993                      :::*                        LISTEN      4889/dovecot       
tcp        0      0 :::995                      :::*                        LISTEN      4889/dovecot       
tcp        0      0 :::110                      :::*                        LISTEN      4889/dovecot       
tcp        0      0 :::143                      :::*                        LISTEN      4889/dovecot       
[root@mail docs]# vim /etc/dovecot.conf

禁掉：795-828

869   passdb sql {
870     # Path for SQL configuration file, see doc/dovecot-sql-example.conf
871     args =/etc/dovecot-mysql.conf
872   }

930   userdb sql {
931     # Path for SQL configuration file, see doc/dovecot-sql-example.conf
932     args =/etc/dovecot-mysql.conf
933   }

211 mail_location =maildir:/var/mailbox/%d/%n/Maildir

把userdb的其他相关禁用
  vim /etc/postfix/main.cf
#postfix的配置文件也要改

[root@mail docs]# vim /etc/postfix/main.cf

414 home_mailbox = Maildir/  此行打开
# vim  /etc/dovecot-mysql.conf                
driver = mysql
connect = host=localhost dbname=extmail user=extmail password=extmail
default_pass_scheme = CRYPT
password_query = SELECT username AS user,password AS password FROM mailbox WHERE username = '%u'               

user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE username = '%u'

接下来启动dovecot服务：

# service dovecot start
# chkconfig dovecot on

七、安装Extmail-1.2  （先安装httpd）

1、安装
[root@mail ~]# tar zxvf extmail-1.2.tar.gz

[root@mail ~]# mkdir -pv /var/www/exsuite
mkdir: created directory `/var/www/exsuite'

[root@mail ~]# mv extmail-1.2 /var/www/extsuite/extmail

[root@mail ~]# cp /var/www/extsuite/extmail/webmail.cf.default  /var/www/extsuite/extmail/webmail.cf

2、修改主配置文件
[root@mail ~]# vim /var/www/extsuite/extmail/webmail.cf

部分修改选项的说明：

104 SYS_MESSAGE_SIZE_LIMIT = 5242880

用户可以发送的最大邮件

SYS_USER_LANG = en_US
语言选项，可改作：
 

77 SYS_USER_LANG = zh_CN  简体中文

SYS_MAILDIR_BASE = /home/domains
此处即为您在前文所设置的用户邮件的存放目录，可改作：
127 SYS_MAILDIR_BASE = /var/mailbox

SYS_MYSQL_USER = db_user
SYS_MYSQL_PASS = db_pass
以上两句句用来设置连接数据库服务器所使用用户名、密码和邮件服务器用到的数据库，这里修改为：
 

139 SYS_MYSQL_USER = extmail
140 SYS_MYSQL_PASS = extmail
142 SYS_MYSQL_HOST = localhost
指明数据库服务器主机名，这里默认即可

145 SYS_MYSQL_TABLE = mailbox
146 SYS_MYSQL_ATTR_USERNAME = username
147 SYS_MYSQL_ATTR_DOMAIN = domain
148 SYS_MYSQL_ATTR_PASSWD = password

以上用来指定验正用户登录里所用到的表，以及用户名、域名和用户密码分别对应的表中列的名称；这里默认即可

SYS_AUTHLIB_SOCKET = /var/spool/authdaemon/socket
此句用来指明authdaemo socket文件的位置，这里修改为：
197 SYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

[root@mail ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using mail.bht.com for ServerName
                                                           [  OK  ]
[root@mail ~]# chkconfig httpd on

3、apache相关配置

由于extmail要进行本地邮件的投递操作，故必须将运行apache服务器用户的身份修改为您的邮件投递代理的用户；本例中打开

了apache服务器的suexec功能，故使用以下方法来实现虚拟主机运行身份的指定。此例中的MDA为postfix自带，因此将指定为

[root@mail ~]# vim /etc/httpd/conf/httpd.conf

postfix用户：
 

<VirtualHost 192.168.10.99:80>
ServerName mail.bht.com
DocumentRoot /var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
Alias /extmail /var/www/extsuite/extmail/html
SuexecUserGroup postfix postfix
</VirtualHost>

修改 cgi执行文件属主为apache运行身份用户：
# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

如果您没有打开apache服务器的suexec功能,也可以使用以下方法解决：
# vi /etc/httpd/httpd.conf
 

231 User postfix
232 Group postfix

992 <VirtualHost 192.168.10.99:80>
993 ServerName mail.bht.com
994 DocumentRoot /var/www/extsuite/extmail/html/
995 ScriptAlias /extmail/cgi /var/www/extsuite/extmail/cgi
996 Alias /extmail /var/www/extsuite/extmail/html
997 </VirtualHost>

4、依赖关系的解决

extmail将会用到perl的Unix::syslogd功能，您可以去http://search.cpan.org搜索下载原码包进行安装。
# tar zxvf Unix-Syslog-0.100.tar.gz
 

[root@mail ~]# cd Unix-Syslog-1.1
[root@mail Unix-Syslog-1.1]# perl Makefile.PL
Checking if your kit is complete...
Looks good
Writing Makefile for Unix::Syslog
[root@mail Unix-Syslog-1.1]# make
# make install

5、启动apache服务
# service httpd start
# chkconfig httpd on

八、安装Extman-1.1

1、安装及基本配置

# tar zxvf  extman-1.1.tar.gz
[root@mail ~]# mv extman-1.1 /var/www/extsuite/extman

修改配置文件以符合本例的需要：
 

[root@mail ~]# cp /var/www/extsuite/extman/webman.cf.default /var/www/extsuite/extman/webman.cf
[root@mail ~]# vim /var/www/extsuite/extman/webman.cf

SYS_MAILDIR_BASE = /home/domains
此处即为您在前文所设置的用户邮件的存放目录，可改作：
12 SYS_MAILDIR_BASE = /var/mailbox

修改
SYS_CAPTCHA_ON = 1
为
21 SYS_CAPTCHA_ON = 0   验证文件

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

在apache的主配置文件中Extmail的虚拟主机部分，添加如下两行：
ScriptAlias /extman/cgi /var/www/extsuite/extman/cgi
Alias /extman /var/www/extsuite/extman/html

创建其运行时所需的临时目录，并修改其相应的权限：
#mkdir  -pv  /tmp/extman
#chown postfix.postfix  /tmp/extman

好了，到此为止，重新启动apache服务器后，您的Webmail和Extman已经可以使用了，可以在浏览器中输入指定的虚拟主机的名

称进行访问，如下：
http://mail.bht.com

测试：

客户机：

选择管理即可登入extman进行后台管理了。默认管理帐号为：[email protected]  密码为：extmail*123*

说明：
(1) 如果您安装后无法正常显示校验码，安装perl-GD模块会解决这个问题。如果想简单，您可以到以下地址下载适合您的平台

的rpm包，安装即可：  http://dries.ulyssis.org/rpm/packages/perl-GD/info.html
(2) extman-1.1自带了图形化显示日志的功能；此功能需要rrdtool的支持，您需要安装此些模块才可能正常显示图形日志。

再次点击域名  勾选允许自由注册~

2、配置Mailgraph_ext，使用Extman的图形日志：（下面所需的软件包面要自己下载）

接下来安装图形日志的运行所需要的软件包Time::HiRes、File::Tail和rrdtool，其中前两个包您可以去

http://search.cpan.org搜索并下载获得，后一个包您可以到 http://oss.oetiker.ch/rrdtool/pub/?M=D下载获得；

注意安装顺序不能改换。

安装Time::HiRes
#tar zxvf Time-HiRes-1.9707.tar.gz
#cd Time-HiRes-1.9707
#perl Makefile.PL
#make
#make test
#make install

安装File::Tail
#tar zxvf File-Tail-0.99.3.tar.gz
#cd File-Tail-0.99.3
#perl Makefile.PL
#make
#make test
#make install

安装rrdtool-1.2.23
#tar zxvf rrdtool-1.2.23.tar.gz
#cd rrdtool-1.2.23
#./configure --prefix=/usr/local/rrdtool
#make
#make install

创建必要的符号链接(Extman会到这些路径下找相关的库文件)
#ln -sv /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/auto/RRDs/RRDs.so  

/usr/lib/perl5/5.8.8/i386-linux-thread-multi/
#ln -sv /usr/local/rrdtool/lib/perl/5.8.8/RRDp.pm   /usr/lib/perl5/5.8.5
#ln -sv /usr/local/rrdtool/lib/perl/5.8.8/i386-linux-thread-multi/RRDs.pm   /usr/lib/perl5/5.8.8

复制mailgraph_ext到/usr/local，并启动之
# cp -r /var/www/extsuite/extman/addon/mailgraph_ext  /usr/local 
# /usr/local/mailgraph_ext/mailgraph-init start

启动cmdserver(在后台显示系统信息)
# /var/www/extsuite/extman/daemon/cmdserver --daemon

添加到自动启动队列
# echo “/usr/local/mailgraph_ext/mailgraph-init start” &gt;&gt; /etc/rc.d/rc.local
# echo “/var/www/extsuite/extman/daemon/cmdserver -v -d” &gt;&gt; /etc/rc.d/rc.local

使用方法： 等待大约15分钟左右，如果邮件系统有一定的流量，即可登陆到extman里，点“图形日志”即可看到图形化的日志

。具体每天，周，月，年的则点击相应的图片进入即可。
