安装前的准备工作
关闭防火墙与SELinux

1. [root@mail ~]# service iptables stop
   
2. iptables：清除防火墙规则：                                 [确定]
   
3. iptables：将链设置为政策 ACCEPT：filter                    [确定]
   
4. iptables：正在卸载模块：                                   [确定]
   
5. [root@mail ~]# service ip6tables stop
   
6. ip6tables：清除防火墙规则：                                [确定]
   
7. ip6tables：将 chains 设置为 ACCEPT 策略：filter            [确定]
   
8. ：正在卸载模块：                                           [确定]
   
9. [root@mail ~]# chkconfig iptables off
   
10. [root@mail ~]# chkconfig ip6tables off
    
11. [root@mail ~]# vim /etc/selinux/config
    
12. # This file controls the state of SELinux on the system.
    
13. # SELINUX= can take one of these three values:
    
14. #     enforcing - SELinux security policy is enforced.
    
15. #     permissive - SELinux prints warnings instead of enforcing.
    
16. #     disabled - No SELinux policy is loaded.
    
17. SELINUX=disabled
    
18. # SELINUXTYPE= can take one of these two values:
    
19. #     targeted - Targeted processes are protected,
    
20. #     mls - Multi Level Security protection.
    
21. SELINUXTYPE=targeted

复制代码

[root@mail ~]# reboot  (要重启生效)
修改主机名

1. [root@mail ~]# vim /etc/sysconfig/network
   
2. NETWORKING=yes
   
3. HOSTNAME=mail.brahmaol.com
   
4. [root@mail ~]# reboot
   
5. [root@mail mail]# cat /etc/hosts
   
6. 10.0.0.253  mail.brahmaol.com
   
7. 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
   
8. ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
   
9. [root@mail mail]#

复制代码

创建一个vmail用户，用作管理虚拟邮箱的文件夹

1. [root@mail mail]#useradd -u 2000 -d /var/vmail -m -s /sbin/nologin vmail

复制代码

安装mysql/dovecot/httpd/php，由于RPM存在依赖关系采用YUM安装（这个安装非常的方便 ），

1. [root@mail mail]# yum install mysql mysql-server msyql-devel dovecot dovecot-mysql php php-imap php-mbstring httpd

复制代码

安装完之后把mysqld dovecot httpd 设置为开机自启动 命令为：chkconfig xxxx on   

启动数据库：
service mysqld start

1. [root@mail mail]# /usr/bin/mysqladmin -u root password 'root'

复制代码

然后为postfixadmin建立相关数据


接下来配置postfixadmin ,这个到官网去下载，然后将其解压到‘html’目录下。 下载链接可以到网上找

1. [root@mail ~]# tar zxvf postfixadmin-2.92.tar.gz
   
2. [root@mail ~]# mv postfixadmin-2.92.tar.gz   adminmail  
   
3. [root@mail ~]# cp -r adminmail /var/www/html/
   

复制代码

编辑postfixadmin配置文件

1. [root@mail ~]# vim /var/www/html/adminmail/config.inc.php
   
2. $CONF['configured'] = fslah;    #改为true  
   
3. $CONF['default_language'] = 'en';   #改为cn
   
4. $CONF['database_type'] = 'mysql';     #这里改为你的数据库类型，按版本区分
   
5. $CONF['database_host'] = 'localhost';
   
6. $CONF['database_user'] = 'postfix';     #这里改为数据库的用户名
   
7. $CONF['database_password'] = 'postfix';  #这里改为数据库的密码
   
8. $CONF['database_name'] = 'postfix';    #这里改为存放邮件数据库的名字
   
9. $CONF['emailcheck_resolve_domain']='YES';   #如果你没做MX记录的话，将此项改为NO,

复制代码

修改文件权限

1. [root@mail adminmail]# cd /var/www/html/adminmail/
   
2. [root@mail adminmail]# chmod 777 templates_c
   
3. [root@mail adminmail]# service httpd start
   
4. [root@mail adminmail]# service dovecot start

复制代码

测试postfixadmin，进入：IP/adminmail/setup.php



创建postfixadmin后台管理密码并修改配置文件，我设置的密码是...秘密....

1. [root@mail adminmail]# vim /var/www/html/adminmail/config.inc.php
   
2. $CONF['setup_password'] = 'c6014f0e7adc2dc05bbfda1e3c83b1b9:506812960c3fe7cb8853e41923b11dc33b969983';
   

复制代码

输入你刚才设置的密码，在输入你新建的管理员的帐号密码
出现下图就是成功建立了帐号


在进入：ip/adminmail    登录postfixadmin,登录之后新建你的域名和邮件帐号


现在来配置postfix 了，它有俩个主要配置文件，在/etc/postfix目录下的main.cf master.cf  

1. [root@mail postfix]# vim main.cf     先修改基本的配置
   
2. mydomain = brahmaol.com    #改为你邮件的域名
   
3. myhostname = mail.brahmaol.com  #改为你的主机名
   
4. mynetworks-style = subnet
   
5. mynetworks = 172.168.96.0/24   #改为你的网段
   
6. home_mailbox = Maildir         
   
7. inet_interfaces = all               
   
8. inet_protocols = all
   
9. #--------------------以下内容为新添加-------------------------
   
10. virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
    
11. virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
    
12. virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
    
13. # Additional for quota support
    
14. virtual_create_maildirsize = yes
    
15. virtual_mailbox_extended = yes
    
16. virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf   
    
17. virtual_mailbox_limit_override = yes
    
18. virtual_maildir_limit_message = Sorry, this user has exceeded their disk space quota, please try again later.
    
19. virtual_overquota_bounce = yes
    
20. #Specify the user/group that owns the mail folders. I'm not sure if this is strictly necessary when using Dovecot's LDA.
    
21. virtual_uid_maps = static:2000    #这是新建虚拟用户的ID
    
22. virtual_gid_maps = static:2000    #这是新建虚拟组的ID
    
23. virtual_mailbox_base = /var/vmail    #邮件存放位置
    
24. #----------------------smtp----------------------------------
    
25. smtpd_sasl_auth_enable = yes     #开启认证
    
26. smtpd_sasl_type = dovecot          #认证类型
    
27. dovecot_destination_recipient_limit = 1
    
28. smtpd_sasl_path = /var/run/dovecot/auth-client
    
29. smtpd_sasl_security_options = noanonymous
    
30. broken_sasl_auth_clients = yes
    
31. smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

新建postfix连接数据库查询的文件。 链接数据库的帐号密码请按照实际情况修改

1. 
   
2. [root@mail postfix]# vim /etc/postfix/mysql_virtual_domains_maps.cf
   
3. user = postfix
   
4. password = postfix
   
5. hosts = localhost
   
6. dbname = postfix
   
7. query = SELECT domain FROM domain WHERE domain='%s' AND active = '1'
   
8. [root@mail ~]# vim /etc/postfix/mysql_virtual_alias_maps.cf
   
9. user = postfix
   
10. password = postfix
    
11. hosts = localhost
    
12. dbname = postfix
    
13. query = SELECT goto FROM alias WHERE address='%s' AND active = '1'
    
14. [root@mail postfix]# vim /etc/postfix/mysql_virtual_mailbox_maps.cf
    
15. user = postfix
    
16. password = postfix

18. dbname = postfix
    
19. query = SELECT CONCAT(domain,'/',maildir) FROM mailbox WHERE username='%s' AND active = '1'
    
20. [root@mail postfix]# vim /etc/postfix/mysql_virtual_mailbox_limit_maps.cf
    
21. user = postfix
    
22. password = postfix
    
23. hosts = localhost
    
24. dbname = postfix
    
25. query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1'

dovecot 配置文件 （由于修改的文件太多，我就不一一列出，直接改/etc/dovecot/dovecot.conf 文件就可以）

1. 
   
2. [root@mail postfix]# doveconf -n
   
3. # 2.0.9: /etc/dovecot/dovecot.conf
   
4. # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) ext4

10. }
    
11. disable_plaintext_auth = no
    
12. listen = *
    
13. mail_location = maildir:/var/vmail/%d/%d/%n    #命令指定客户端接收邮件到哪个目录请按照实际情况修改

17.   driver = sql
    
18. }
    
19. protocols = imap pop3
    
20. service auth {

45. }
    
46. [root@mail postfix]#

新建dovecot-sql.conf.ext与dovecot-dict-sql.conf.ext 文件

1. [root@mail postfix]# vim /etc/dovecot/dovecot-sql.conf.ext
   
2. driver = mysql
   
3. connect = host=localhost dbname=postfix user=postfix password=postfix
   
4. default_pass_scheme = MD5
   
5. user_query = SELECT CONCAT('/var/vmail/', maildir) AS home, 2000 AS uid, 2000 AS gid, CONCAT('*:bytes=', quota) as quota_rule FROM mailbox WHERE username = '%u' AND active='1'
   
6. password_query = SELECT username AS user, password, CONCAT('/var/vmail/', maildir) AS userdb_home, 2000 AS userdb_uid, 2000 AS userdb_gid, CONCAT('*:bytes=', quota) as userdb_quota_rule FROM mailbox WHERE username = '%u' AND active='1'
   
7. [root@mail postfix]# vim /etc/dovecot/dovecot-dict-sql.conf.ext
   
8. connect = host=localhost dbname=postfix user=postfix password=postfix
   
9. map {
   
10.   pattern = priv/quota/storage
    
11.   table = quota2
    
12.   username_field = username
    
13.   value_field = bytes
    
14. }
    
15. map {
    
16.   pattern = priv/quota/messages
    
17.   table = quota2
    
18.   username_field = username
    
19.   value_field = messages
    
20. }

到此，配置结束。现在可以进行测试邮件服务器是否正常工作  由于该文档是在我搭建了服务器之后才写的，有些地方可能没写到位，如果有报错的地方多看日志，
下面说下我在测试时遇到的问题。可以pop3/IMAP登录，发信也没问题，可对方收不到邮件，对方发给我的邮件也收不到，查看日志没有报错，在/var/vmail/域名/域名/user/new   可以看到对方发过来的邮件。可是客户端获取不到邮件，这种情况的话就要修改配置文件
vim /etc/dovecot/conf.d/10-mail.conf
mail_location = maildir:/var/vmail/%d/%d/%n  》根据邮件位置修改

然后在保存重启dovecot 服务后一切正常！！！   有问题欢迎联系我，大家一起讨论

  为毛出现个不相关的图片

dbsrv

http:/IP/postfixadmin建立虚拟用户的时候，无法在磁盘上创建用户文件夹，mysql里倒是写入了。

virtual_mailbox_base = /var/mail/vmail/

postfixadmin的日志在哪里？不在log/message里？
改过主机名有影响么？

lambkinxmm

我也正在安装postfixadmin可是建立的虚拟用户，却无法收取邮件，提示密码错误....vmail下也没有用户的邮件文件创建,能不能指点一二.谢谢~
