  • 邮件系统的集成版本,你可能听说过吧!!!!

    转自社区:https://www.centos.bz/2012/04/postfix-dovecot-mysql-postfixadmin-roundcube/#安装dovecot

    postfix+dovecot+mysql+postfixadmin+roundcube

    实现Web收发的邮件系统方案，利用postfix作为SMTP服务器，实现邮件的发送与接收，使用dovecot作为IMAP服务器，roundcube作为web MUA(邮件用户代理)，实现web在线邮件发送与接收。而postfix的虚拟域名和虚拟用户则由postfixadmin管理。

    系统及软件环境

    系统:centos-5.8 32位
    软件：postfix-2.8.7，dovecot-1.0.7,apache-2.2.22,php-5.2.17,mysql-5.1.58，postfixadmin-2.3.5，roundcubemail-0.7.2
    注意：本教程并不通用，使用不同的软件版本可能配置方法不一样， 请注意。

    安装LAMP

    1、第三方库添加
    由于postfixadmin要求php-5.2以上的版本，且我们这里使用yum安装lamp，默认的版本是5.1，所以需要添加第三方的rpm库安装php 5.2版本。

    1. rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
    2. vi /etc/yum.repos.d/CentOS-Base.repo

    加入：

    1. [utterramblings]
    2. name=Jason's Utter Ramblings Repo
    3. baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
    4. enabled=1
    5. gpgcheck=1
    6. gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

    2、开始安装

    1. yum -y install httpd mysql mysql-devel mysql-server php php-pecl-Fileinfo php-mcrypt php-devel php-mysql hp-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc pcre pcre-devel

    3、启动服务

    1. service httpd start
    2. service mysqld start
    3. mysqladmin -uroot password 'mysql密码'

    安装postfix

    由于centos自带的postfix不支持mysql,所以只能选择编译安装。
    首先删除自带的sendmail

    1. rpm -e sendmail
    1. yum install db4-devel
    2. groupadd -g 1001 postfix
    3. groupadd postdrop
    4. useradd -M -u 1001 -g postfix  -s /sbin/nologin postfix
    5. cd /tmp
    6. wget http://postfix.energybeam.com/source/official/postfix-2.8.7.tar.gz
    7. tar xzf postfix-2.8.7.tar.gz
    8. cd postfix-2.8.7
    9. make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql'   'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm'
    10. make && make install

    简单配置一下postfix:

    1. vi /etc/postfix/main.cf

    添加如下代码：

    1. virtual_mailbox_base = /var/mail/vmail
    2. virtual_uid_maps = static:1001
    3. virtual_gid_maps = static:1001

    1001分别为postfix用户和postfix用户组的id

    安装dovecot

    1. yum -y install dovecot

    安装postfixadmin

    1. cd /tmp
    2. wget http://softlayer.dl.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin-2.3.5/postfixadmin-2.3.5.tar.gz
    3. tar xzf postfixadmin-2.3.5.tar.gz -C /var/www/html
    4. mv /var/www/html/postfixadmin-2.3.5 /var/www/html/postfixadmin
    5. cd /var/www/html/postfixadmin
    6. mysql -uroot -p
    7. mysql > CREATE DATABASE postfix;
    8. mysql > CREATE USER 'postfix'@'localhost' IDENTIFIED BY 'postfix_password';
    9. mysql > GRANT ALL PRIVILEGES ON `postfix` . * TO 'postfix'@'localhost';

    postfix_password替换成自己的。
    修改配置文件：

    1. vi config.inc.php

    找到下面的参数并作修改：

    1. $CONF['configured'] = true;
    2. $CONF['database_password'] = 'postfix_password';
    3. $CONF['default_language'] = 'cn';
    4. $CONF['used_quotas'] = 'YES';
    5. $CONF['quota'] = 'YES';

    postfix_password即上一步设置的postfix用户密码。
    打开浏览器，输入下面的网址开始安装：
    http://your-domain/postfixadmin/setup.php

    postfix与postfixadmin整合

    1. vi /etc/postfix/main.cf

    按如下添加或修改：

    1. virtual_mailbox_domains = proxy:mysql:/etc/postfix/sql/mysql_virtual_domains_maps.cf
    2. virtual_alias_maps =
    3.    proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_maps.cf,
    4.    proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_maps.cf,
    5.    proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_catchall_maps.cf
    6. virtual_mailbox_maps =
    7.    proxy:mysql:/etc/postfix/sql/mysql_virtual_mailbox_maps.cf,
    8.    proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_mailbox_maps.cf
    9.   
    10. # Additional for quota support
    11. virtual_create_maildirsize = yes
    12. virtual_mailbox_extended = yes
    13. virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf
    14. virtual_mailbox_limit_override = yes
    15. virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.
    16. virtual_overquota_bounce = yes

    建立目录sql

    1. mkdir /etc/postfix/sql

    以下的几个文件注意修改postfix_password。

    1. vi /etc/postfix/sql/mysql_virtual_alias_maps.cf

    内容：

    1. user = postfix

    按如下修改或添加:

    1. default_mail_env = maildir:/var/mail/vmail/%u/
    2.  
    3. auth default {
    4.   mechanisms plain
    5.   userdb sql {
    6.     # Path for SQL configuration file, see doc/dovecot-sql-example.conf
    7.     args = /etc/dovecot-mysql.conf
    8.   }
    9.   passdb sql {
    10.     # Path for SQL configuration file, see doc/dovecot-sql-example.conf
    11.     args = /etc/dovecot-mysql.conf
    12.   }
    13. }
    14.  
    15. # Valid UID range for users, defaults to 500 and above.
    16. first_valid_uid = 1001  # Change this to your postfix UID
    17.  
    18. ## IMAP quota

    30.   mail_plugins = quota
    31. }
    32.  
    33. ## Dictionary DB proxy
    34. dict {
    35.   quota = mysql:/etc/dovecot-dict-quota.conf
    36. }
    37.  
    38. ## Default quota values
    39. plugin {
    40. quota = dict:storage=200000 proxy::quota
    41. }

    以下两个文件注意修改postfix_password。

    1. vi /etc/dovecot-mysql.conf

    内容：

    1. connect = host=localhost dbname=postfix user=postfix password=postfix_password
    2. driver = mysql
    3.  
    4. # Default password scheme.
    5. # depends on your $CONF['encrypt'] setting:
    6. # md5crypt  -> MD5-CRYPT
    7. # md5       -> PLAIN-MD5
    8. # cleartext -> PLAIN
    9. default_pass_scheme = MD5-CRYPT
    10.  
    11. # Query to retrieve password. user can be used to retrieve username in other
    12. # formats also.
    13.  
    14. password_query = SELECT username AS user,password FROM mailbox WHERE username = '%u' AND active='1'
    15.  
    16. # Query to retrieve user information.
    17.  
    18. user_query = SELECT maildir, 1001 AS uid, 1001 AS gid, CONCAT('dict:storage=',floor(quota/1000),' proxy::quota') as quota FROM mailbox WHERE username = '%u' AND active='1'
    1. vi /etc/dovecot-dict-quota.conf

    内容：

    1. driver = mysql
    2. connect = host=localhost dbname=postfix user=postfix password=postfix_password
    3. default_pass_scheme = MD5-CRYPT
    4. table = quota
    5. select_field = current
    6. where_field = path
    7. username_field = username

    启动服务

    1. postmap /etc/aliases
    2. /usr/sbin/postfix start
    3. service dovecot start

    roundcube安装

    1. cd /tmp
    2. wget http://voxel.dl.sourceforge.net/project/roundcubemail/roundcubemail/0.7.2/roundcubemail-0.7.2.tar.gz
    3. tar xzf roundcubemail-0.7.2.tar.gz  -C /var/www/html
    4. mv /var/www/html/roundcubemail-0.7.2 /var/www/html/webmail
    5. mysql -uroot -p
    6. mysql> CREATE DATABASE roundcubemail;
    7. mysql> GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost IDENTIFIED BY 'password';
    8. mysql> FLUSH PRIVILEGES;

    现在你可以浏览器打开以下网址安装：
    http://yourdomain/webmail/installer/
    详细的roundcubemail安装说明可以参考：http://blog.dvxj.com/pandola/roundcube-install-config.html
    这样就实现了完整的邮件系统功能，没有实现的是smtp的认证，即无法使用像outlook express客户端发送邮件，如有需要，可以搜索sasl方面的教程配置。
