篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Mail搭建邮件服务器（Postfix+Dovcot+Mysql+Roundcubemail）相关的知识，希望对你有一定的参考价值。

大纲 

　　一、mail部署说明

　　二、安装准备

　　三、LMAP环境配置

　　四、配置postfixadmin

　　五、配置postfix

　　六、配置dovecot

　　七、测试SMTP和POP3服务

　　八、配置Roundcubemail

一、mail部署说明

  •  　　操作系统：Linux（CentOS6.5）
  • 　　本例采用的是LAMP+Postfix+Dovcot+PostfixAdmin+Roundcubemail搭建的邮件服务器。阅读本例请先参考：【Mail】邮件的基础知识和原理。
          LAMP一种软件环境，Postfix：一种邮件传输代理软件，通常用来发送邮件；Dovcot：邮件检索代理软件，通常用来接收邮件；PostfixAdmin：是一个基于Web的 Postfix 邮件发送服务器的管理工具；Roundcubemail：采用php+Ajax开发并且需要mysql数据库来存储数据的email客户端。
  •       邮件发送和接收流程如下图：
          
               发送流程：客户端Mail Client发出邮件 ——> Postfix接收，通过Dovecot进行认证(查询数据库是否存在用户) ——> Dovecot把邮件存放在本地　　       （Mail Dir）
               接收流程：客户端WebMail发出获取邮件请求  ——> Dovecot接收请求，验证用户（查询数据库是否存在用户）——> Dovecot把邮件从本地拿出，交给客户端。　　

二、安装准备

  1. 添加DNS解析记录　　
    • 先添加 A 记录 mail.yourdomain.com 解析为你的邮件服务器IP
    • 再添加 MX 记录指向 mail.yourdomain.com

  2. 关闭防火墙与SELinux
    • 关闭防火墙命令：service iptables stop
    • 关闭SELinux命令：vim /etc/selinux/config
  3. 配置hostname
    • 修改主机名命令：vim /etc/sysconfig/network
  4. 配置软件源
    • 配置好yun，保证云能正常安装软件


  5. 创建一个vmail用户，用作管理虚拟邮箱的文件夹

    　　useradd -u 2000 -d /var/vmail -m -s /sbin/nologin vmail

三、LMAP环境配置

         

四、配置postfixadmin

  1. 下载postfixadmin，地址：https://sourceforge.net/projects/postfixadmin/，本例使用的是postfixadmin-2.93.tar.gz。
  2. 解压到apache的网页目录（/var/www/html/）并修改文件名:
    1 [root@mail ~]# tar xf postfixadmin-2.93.tar.gz -C /var/www/html/
2 [root@mail ~]# cd /var/www/html/
3 [root@mail html]# ls
4 index.php  postfixadmin-2.93
5 [root@mail html]# mv postfixadmin-2.93 postfixadmin
6 [root@mail html]# ls
7 index.php  postfixadmin
8 [root@mail html]#
  3. 配置并测试
     1 [root@mail html]# cd postfixadmin/ 
 2 #修改前先备份一下配置文件 
 3 [root@mail postfixadmin]# cp config.inc.php config.inc.php.bak 
 4 [root@mail postfixadmin]# cp setup.php setup.php.bak 
 5 [root@mail postfixadmin]# vim config.inc.php 
 6 #找到下面几行并修改 
 7 $CONF[\'configured\'] = true; 
 8 $CONF[\'database_type\'] = \'mysql\'; 
 9 $CONF[\'database_host\'] = \'localhost\'; 
10 $CONF[\'database_user\'] = \'postfix\'; 
11 $CONF[\'database_password\'] = \'postfix\'; 
12 $CONF[\'database_name\'] = \'postfix\'; 
13 $CONF[\'admin_email\'] = \'postmaster@free.com\'; 
14 $CONF[\'encrypt\'] = \'dovecot:CRAM-MD5\'; 
15 $CONF[\'dovecotpw\'] = "/usr/bin/doveadm pw"; 
16 $CONF[\'domain_path\'] = \'YES\'; 
17 $CONF[\'domain_in_mailbox\'] = \'NO\'; 
18 $CONF[\'aliases\'] = \'1000\'; 
19 $CONF[\'mailboxes\'] = \'1000\'; 
20 $CONF[\'maxquota\'] = \'1000\'; 
21 $CONF[\'fetchmail\'] = \'NO\'; 
22 $CONF[\'quota\'] = \'YES\'; 
23 $CONF[\'used_quotas\'] = \'YES\'; 
24 $CONF[\'new_quota_table\'] = \'YES\';
  4. 为postfixadmin创建Mysql数据库与权限记录　
    • 启动数据库，进入数据库
    • 创建postfix数据库，并创建postfix用户且授权
      1 mysql> create database postfix; 
2 mysql> grant all on postfix.* to postfix@\'localhost\' identified by \'postfix\'; 
3 mysql> flush privileges;
    • 测试postfix能否登录成功。
       1 [root@mail html]# mysql -u postfix -p
 2 Enter password: 
 3 Welcome to the MySQL monitor.  Commands end with ; or \\g.
 4 Your MySQL connection id is 53806
 5 Server version: 5.6.31 MySQL Community Server (GPL)

13 Type \'help;\' or \'\\h\' for help. Type \'\\c\' to clear the current input statement.
14 
15 mysql> show databases;

20 | postfix            | 
21 | test               | 
22 +--------------------+ 
23 3 rows in set (0.00 sec) 
24 mysql> use postfix 
25 Database changed
26 mysql>

        

  5. postfixadmin具体配置流程　
    • 启动apache，由浏览器进入postfix项目的设置界面，地址：http://ip:端口/postfixadmin/setup.php

      注：检查PHP环境，并初始化数据库
    • 可以看出上面步骤在跟新了数据库postfix
    • 创建设置密码，修改配置文件的设置密码

      点击生成hash码秘钥（Generate password hash）。
    • 刷新界面，设置超级管理员账号
    • 点击新增，应该会出现错误，说没有dovecotpw，是因为我们还没安装dovecot。
    • 这里先来安装一下dovecot,后面再进行配置！ 
      1 [root@mail postfixadmin]# yum install -y  dovecot dovecot-devel dovecot-mysql 
2 [root@mail postfixadmin]# chkconfig dovecot on #加入开机自启动 
3 [root@mail postfixadmin]# chkconfig dovecot --list 
4 dovecot         0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭 
5 [root@mail postfixadmin]#

       

    • 再来设置一下管理员的账户与密码
    • 进入postfixadmin登入界面，地址：http://ip:端口/postfixadmin/login.php，输入管理员账号和密码登录


  6. postfxiadmin不能自动创建目录，得增加自动建立目录的功能　
    • 建立创建虚拟邮箱脚本,脚本名称 /usr/local/bin/maildir-creation.sh，脚本内容如下:
      注：邮件文件就保存在HOME_DIR（及/var/vamai）中，自己可以下载查看
       1 [root@mail ~]#vim /usr/local/bin/maildir-creation.sh 
 2 #!/bin/bash 
 3 # 
 4 HOME_DIR="/var/vmail"
 5 USER_NAME="vmail"
 6 GROUP_NAME="vmail"
 7 if [ ! -d ${HOME_DIR}/$1 ] ; then
 8     mkdir ${HOME_DIR}/$1 
 9     chown -R ${USER_NAME}.${GROUP_NAME} ${HOME_DIR}/$1 
10 fi
11 mkdir ${HOME_DIR}/$1/$2 
12 chown -R ${USER_NAME}.${GROUP_NAME} ${HOME_DIR}/$1/$2
    • 建立删除虚拟邮箱脚本，脚本名称 /usr/local/bin/maildir-deletion.sh ,脚本内容如下:
       1 [root@mail ~]#vim /usr/local/bin/maildir-deletion.sh 
 2 #!/bin/bash 
 3 # 
 4 # vmta ALL = NOPASSWD: /usr/local/bin/maildir-deletion.sh 
 5 # 
 6 if [ $# -ne 2 ] ; then 
 7   exit 127 
 8 fi
 9 DOMAIN="$1"
10 USER="$2"
11 HOME_DIR="/var/vmail"
12 USER_DIR="${HOME_DIR}/${DOMAIN}/${USER}"
13 TRASH_DIR="${HOME_DIR}/deleted-maildirs"
14 DATE=`date "+%Y%m%d_%H%M%S"` 
15 if [ ! -d "${TRASH_DIR}/${DOMAIN}" ] ; then
16     mkdir -p "${TRASH_DIR}/${DOMAIN}"
17 fi
18 if [ -d "${USER_DIR}" ] ; then
19     mv ${USER_DIR} ${TRASH_DIR}/${DOMAIN}/${USER}-${DATE} 
20 fi
  7. 建立删除目录
    1 [root@mail ~]# mkdir /var/vmail/deleted-maildirs 
2 [root@mail ~]# chown -R vmail.vmail /var/vmail/deleted-maildirs/
  8. 赋予脚本可执行权限
    1 [root@mail ~]# chmod 750 /usr/local/bin/maildir-* 
2 [root@mail ~]# chown vmail.vmail /usr/local/bin/maildir-*
  9. 配置sudo
    1 [root@mail ~]#vim /etc/sudoers 
2 #在 /etc/sudoers 最后增加两行 
3 vmail ALL = NOPASSWD: /usr/local/bin/maildir-creation.sh 
4 vmail ALL = NOPASSWD: /usr/local/bin/maildir-deletion.sh 
5 #在/etc/sudoers 注释掉下面内容 
6 #Defaults    requiretty 
7 ：wq! #由于这个文件是只读的，所以得强制保存并退出
  10. 修改postfixadmin的相关文件
     1 [root@mail ~]# cd /var/www/html/postfixadmin/ 
 2 [root@mail postfixadmin]# vim create-mailbox.php 
 3 修改create-mailbox.php 文件，229行内容应该是： 
 4 db_log ($SESSID_USERNAME, $fDomain, \'create_mailbox\', "$fUsername"); 
 5 在该行前面增加下面一行, 
 6 system("sudo /usr/local/bin/maildir-creation.sh $fDomain ".$_POST[\'fUsername\']); 
 7 [root@mail postfixadmin]# vim delete.php 
 8 修改delete.php 文件，146行内容应该是, 
 9 db_log ($SESSID_USERNAME, $fDomain, \'delete_mailbox\', $fDelete); 
10 在该行下面增加下面4行, 
11 $userarray=explode("@",$fDelete); 
12 $user=$userarray[0]; 
13 $domain=$userarray[1]; 
14 system("sudo /usr/local/bin/maildir-deletion.sh $domain $user");

    ------------------------------至此postfixadmin配置全部完成---------------------------

五、配置Postfix

　　注：Postfix用CentOS6.5系统自带的，因为CentOS6.5里面的postfix包已经支持mysql

  1. 查看postfix版本
    1 [root@mail deleted-maildirs]# rpm -qa | grep postfix 
2 postfix-2.6.6-6.el6_7.1.x86_64
  2. 修改postfix的配置文件
     1 [root@mail ~]# vim /etc/postfix/main.cf 
 2 #基本配置 
 3 myhostname = mail.yourdomain.com 
 4 mydomain = yourdomain.com 
 5 myorigin = $mydomain 
 6 inet_interfaces = all 
 7 mynetworks_style = host 
 8 mynetworks = 192.168.18/24, 127.0.0.0/8
 9 #虚拟域名配置 
10 virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql_virtual_domains_maps.cf 
11 virtual_alias_maps = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf 
12 virtual_mailbox_maps = proxy: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
22 virtual_gid_maps = static:2000
23 #Specifies which tables proxymap can read: http://www.postfix.org/postconf.5.html#proxy_read_maps 
24 proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps 
25 [root@mail ~]# postconf #检查配置文件是否有错误
  3. 创建Mysql脚本　
    • 创建/etc/postfix/mysql_virtual_domains_maps.cf文件
      1 [root@mail ~]# vim /etc/postfix/mysql_virtual_domains_maps.cf 
2 user = postfix 
3 password = postfix 
4 hosts = localhost 
5 dbname = postfix 
6 query = SELECT domain FROM domain WHERE domain=\'%s\' AND active = \'1\'
7 #optional query to use when relaying for backup MX 
8 #query = SELECT domain FROM domain WHERE domain=\'%s\' AND backupmx = \'0\' AND active = \'1\'
    • 创建/etc/postfix/mysql_virtual_alias_maps.cf文件
      1 [root@mail ~]# vim /etc/postfix/mysql_virtual_alias_maps.cf 
2 user = postfix 
3 password = postfix 
4 hosts = localhost 
5 dbname = postfix 
6 query = SELECT goto FROM alias WHERE address=\'%s\' AND active = \'1\'
    • 创建/etc/postfix/mysql_virtual_mailbox_maps.cf文件
      1 [root@mail ~]# vim /etc/postfix/mysql_virtual_mailbox_maps.cf 
2 user = postfix 
3 password = postfix 
4 hosts = localhost 
5 dbname = postfix 
6 query = SELECT CONCAT(domain,\'/\',maildir) FROM mailbox WHERE username=\'%s\' AND active = \'1\'
    • 创建/etc/postfix/mysql_virtual_mailbox_limit_maps.cf文件
      1 [root@mail ~]# vim /etc/postfix/mysql_virtual_mailbox_limit_maps.cf 
2 user = postfix 
3 password = postfix 
4 hosts = localhost 
5 dbname = postfix 
6 query = SELECT quota FROM mailbox WHERE username=\'%s\' AND active = \'1\'
  4. SMTP 认证设定
    SMTP（Simple Mail Transfer Protocol）即简单邮件传输协议,它是一组用于由源地址到目的地址传送邮件的规则，由它来控制信件的中转方式　
    • 查看postfix支持的认证，默认支持dovecot
    • 1 [root@mail ~]# postconf -a 
2 cyrus 
3 dovecot
    • 修改/etc/postfix/main.cf配置文件
       1 [root@mail ~]#vim /etc/postfix/main.cf 
 2 #SASL SUPPORT FOR CLIENTS 
 3 # Turns on sasl authorization 
 4 smtpd_sasl_auth_enable = yes 
 5 #Use dovecot for authentication 
 6 smtpd_sasl_type = dovecot 
 7 # Path to UNIX socket for SASL 
 8 smtpd_sasl_path = /var/run/dovecot/auth-client 
 9 #Disable anonymous login. We don\'t want to run an open relay for spammers. 
10 smtpd_sasl_security_options = noanonymous 
11 #Adds support for email software that doesn\'t follow RFC 4954. 
12 #This includes most versions of Microsoft Outlook before 2007. 
13 broken_sasl_auth_clients = yes 
14 # 
15 smtpd_recipient_restrictions =  permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination


  5. 使用Dovecot做为投递
    1 [root@mail ~]# vim /etc/postfix/main.cf 
2 # TRANSPORT MAP 
3 virtual_transport = dovecot 
4 dovecot_destination_recipient_limit = 1 
5 #修改master.cf文件 
6 [root@mail ~]# vim /etc/postfix/master.cf 
7 #在最后增加这两行,注意flags前面有两个空格，不然会报错 
8 dovecot   unix  -       n       n       -       -       pipe， 
9   flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}

    ------------------------------至此postfix配置全部完成---------------------------

六、配置Dovecot

  1. 前面已经安装了dovecot，现在配置dovecot的配置文件　
    • 修改/etc/dovecot/dovecot.conf #主配置文件
      1 [root@mail ~]# vim /etc/dovecot/dovecot.conf 
2 protocols = imap pop3 
3 listen = * 
4 dict { 
5   quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext 
6 } 
7 !include conf.d/*.conf
    • 修改/etc/dovecot/conf.d/10-auth.conf
      1 [root@mail ~]# vim /etc/dovecot/conf.d/10-auth.conf 
2 disable_plaintext_auth = no 
3 auth_mechanisms = plain login cram-md5 
4 !include auth-sql.conf.ext
    • 修改/etc/dovecot/conf.d/10-mail.conf
      1 [root@mail ~]# vim /etc/dovecot/conf.d/10-mail.conf 
2 mail_location = maildir:%hMaildir 
3 mbox_write_locks = fcntl
    • 修改/etc/dovecot/conf.d/10-master.conf
       1 [root@mail ~]# vim /etc/dovecot/conf.d/10-master.conf 
 2 service imap-login { 
 3   inet_listener imap { 
 4   } 
 5   inet_listener imaps { 
 6   } 
 7 } 
 8 service pop3-login { 
 9   inet_listener pop3 { 
10   } 
11   inet_listener pop3s { 
12   } 
13 } 
14 service lmtp { 
15   unix_listener lmtp { 
16   } 
17 } 
18 service imap { 
19 } 
20 service pop3 { 
21 } 
22 service auth { 
23   unix_listener auth-userdb { 
24     mode = 0600 
25     user = vmail 
26     group = vmail 
27   } 
28 #新加下面一段，为smtp做认证 
29   unix_listener auth-client { 
30     mode = 0600 
31     user = postfix 
32     group = postfix 
33   } 
34 } 
35 service auth-worker { 
36 } 
37 service dict { 
38   unix_listener dict { 
39     mode = 0600 
40     user = vmail 
41     group = vmail 
42   } 
43 }
    • 修改/etc/dovecot/conf.d/15-lda.conf
      1 [root@mail ~]# vim /etc/dovecot/conf.d/15-lda.conf 
2 protocol lda { 
3   mail_plugins = quota
4   postmaster_address = postmaster@free.com #管理员邮箱 
5 }
    • 修改/etc/dovecot/conf.d/20-imap.conf
      1 [root@mail ~]# vim /etc/dovecot/conf.d/20-imap.conf 
2 protocol imap { 
3         mail_plugins = quota imap_quota 
4 }
    • 修改/etc/dovecot/conf.d/20-pop3.conf
      1 [root@mail ~]# vim /etc/dovecot/conf.d/20-pop3.conf 
2 protocol pop3 { 
3   pop3_uidl_format = %08Xu%08Xv 
4   mail_plugins = quota
5 }
    • 修改/etc/dovecot/conf.d/90-quota.conf
       1 [root@mail ~]# vim /etc/dovecot/conf.d/90-quota.conf 
 2 plugin { 
 3   quota_rule = *:storage=1G 
 4 } 
 5 plugin { 
 6 } 
 7 plugin { 
 8   quota = dict:User quota::proxy::quota
 9 } 
10 plugin { 
11 }
    • 增加/etc/dovecot/dovecot-sql.conf.ext
      1 [root@mail ~]# vim /etc/dovecot/dovecot-sql.conf.ext 
2 driver = mysql 
3 connect = host=localhost dbname=postfix user=postfix password=postfix 
4 default_pass_scheme = CRAM-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\'
    • 增加/etc/dovecot/dovecot-dict-sql.conf.ext
       1 [root@mail ~]# vim /etc/dovecot/dovecot-dict-sql.conf.ext 
 2 connect = host=localhost dbname=postfix user=postfix password=postfix 
 3 map { 
 4   pattern = priv/quota/storage
 5   table = quota2 
 6   username_field = username 
 7   value_field = bytes 
 8 } 
 9 map { 
10   pattern = priv/quota/messages
11   table = quota2 
12   username_field = username 
13   value_field = messages 
14 }
  2. 重新启动postfix和dovecot服务
    1 [root@mail ~]# service postfix restart 
2 关闭 postfix：                                             [确定] 
3 启动 postfix：                                             [确定] 
4 [root@mail ~]# service dovecot restart 
5 停止 Dovecot Imap：                                        [失败] 
6 正在启动 Dovecot Imap：                                    [确定]

 　　　　------------------------------至此dovecot配置全部完成---------------------------

七、测试SMTP和POP3服务

  1. 登录postfixadmin，地址http://ip:端口/postfixadmin/login.php，创建虚拟域


  2. 创建测试邮箱
  3. 使用telnet 进行测试
    请参照：【Mail】telnet收发邮件过程

八、配置Roundcubemail

  1. 下载Roundcubemail（注意下载roundcubmail版本与php版本的兼容问题，本例使用的是roundcubemail-0.9.0.tar.gz），地址：https://roundcube.net，并且解压到apache目录中
    1 [root@mail ~]# tar -xf roundcubemail-0.9.0.tar.gz -C /var/www/html/ 
2 [root@mail ~]# cd /var/www/html/ 
3 [root@mail html]# ls 
4 admin  index.php  phpmyadmin  roundcubemail-0.9.0 
5 [root@mail html]# mv roundcubemail-0.9.0 webmail 
6 [root@mail html]# ls 
7 admin  index.php  phpmyadmin  webmail 
8 [root@mail html]#
  2. 在浏览器中访问roundcubemail的安装界面，地址：http://ip:端口/webmail/installer
  3. 从上面可以看出时区有问题，其他都ok。所以修改php的配置文件。
    • 修改php.ini
      1 [root@mail installer]# vim /etc/php.ini 
2 date.timezone = Asia/Shanghai

       

    • 修改apache中PHPini的位置,并重启apache服务
      1 [root@mail installer]# vim /etc/httpd/conf/httpd.conf 
2 PHPIniDir "/etc/php.ini"
3 [root@mail installer]# service httpd restart 
4 Stopping httpd:                                            [  OK  ] 
5 Starting httpd:                                            [  OK  ] 
6 [root@mail installer]#
  4. 修改所有Web文件的所属者与所属组
     1 [root@mail ~]# cd /var/www/html/ 
 2 [root@mail html]# ll 
 3 total 16 
 4 drwxrwxr-x 14 1000 1010 4096 Jul 11 05:25 admin 
 5 -rw-r--r--  1 root root   18 Jul 11 04:12 index.php 
 6 drwxr-xr-x  9 root root 4096 Jul 11 04:17 phpmyadmin 
 7 drwxr-xr-x 11  501   80 4096 Jun 16 23:10 webmail 
 8 [root@mail html]# chown -R vmail.vmail admin 
 9 [root@mail html]# chown -R vmail.vmail phpmyadmin 
10 [root@mail html]# chown -R vmail.vmail webmail
  5. 查看session保存位置
    1 [root@mail html]# vim /etc/php.ini 
2 session.save_path = "/var/lib/php/session"
  6. 修改session文件的所属组
    1 [root@mail html]# cd /var/lib/php/
