Postfix+dovecot+MySQL+Postfixadmin+roundcube邮件服务器的部署

这篇文章介绍一个实现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。

rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

vi /etc/yum.repos.d/CentOS-Base.repo

加入:

[utterramblings]

name=Jason's Utter Ramblings Repo

baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/

enabled=1

gpgcheck=1

gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

2、开始安装

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

service httpd start

service mysqld start

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

yum install db4-devel

groupadd -g 1001 postfix

groupadd postdrop

useradd -M -u 1001 -g postfix  -s /sbin/nologin postfix

cd /tmp

wget http://postfix.energybeam.com/source/official/postfix-2.8.7.tar.gz

tar xzf postfix-2.8.7.tar.gz

cd postfix-2.8.7

make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql'   'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm'

make && make install

简单配置一下postfix:

添加如下代码:

virtual_mailbox_base = /var/mail/vmail

virtual_uid_maps = static:1001

virtual_gid_maps = static:1001

1001分别为postfix用户和postfix用户组的id

安装dovecot 安装postfixadmin

cd /tmp

wget http://softlayer.dl.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin-2.3.5/postfixadmin-2.3.5.tar.gz

tar xzf postfixadmin-2.3.5.tar.gz -C /var/www/html

mv /var/www/html/postfixadmin-2.3.5 /var/www/html/postfixadmin

cd /var/www/html/postfixadmin

mysql -uroot -p

mysql > CREATE DATABASE postfix;

mysql > CREATE USER 'postfix'@'localhost' IDENTIFIED BY 'postfix_password';

mysql > GRANT ALL PRIVILEGES ON `postfix` . * TO 'postfix'@'localhost';

postfix_password替换成自己的。
修改配置文件:

找到下面的参数并作修改:

$CONF['configured'] = true;

$CONF['database_password'] = 'postfix_password';

$CONF['default_language'] = 'cn';

$CONF['used_quotas'] = 'YES';

$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

按如下添加或修改:

virtual_mailbox_domains = proxy:mysql:/etc/postfix/sql/mysql_virtual_domains_maps.cf

virtual_alias_maps =

   proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_maps.cf,

   proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_maps.cf,

   proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_catchall_maps.cf

virtual_mailbox_maps =

   proxy:mysql:/etc/postfix/sql/mysql_virtual_mailbox_maps.cf,

   proxy:mysql:/etc/postfix/sql/mysql_virtual_alias_domain_mailbox_maps.cf

  

# Additional for quota support

virtual_create_maildirsize = yes

virtual_mailbox_extended = yes

virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf

virtual_mailbox_limit_override = yes

virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.

virtual_overquota_bounce = yes

建立目录sql

以下的几个文件注意修改postfix_password。

vi /etc/postfix/sql/mysql_virtual_alias_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query = SELECT goto FROM alias WHERE address='%s' AND active = '1'

#expansion_limit = 100

vi /etc/postfix/sql/mysql_virtual_alias_domain_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query = SELECT goto FROM alias,alias_domain WHERE alias_domain.alias_domain = '%d' and alias.address = CONCAT('%u', '@', alias_domain.target_domain) AND alias.active = 1 AND alias_domain.active='1'

vi /etc/postfix/sql/mysql_virtual_alias_domain_catchall_maps.cf

内容:

# handles catch-all settings of target-domain

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query  = SELECT goto FROM alias,alias_domain WHERE alias_domain.alias_domain = '%d' and alias.address = CONCAT('@', alias_domain.target_domain) AND alias.active = 1 AND alias_domain.active='1'

vi /etc/postfix/sql/mysql_virtual_domains_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query          = SELECT domain FROM domain WHERE domain='%s' AND active = '1'

#query          = SELECT domain FROM domain WHERE domain='%s'

#optional query to use when relaying for backup MX

#query           = SELECT domain FROM domain WHERE domain='%s' AND backupmx = '0' AND active = '1'

#expansion_limit = 100

vi /etc/postfix/sql/mysql_virtual_mailbox_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query  = SELECT maildir FROM mailbox WHERE username='%s' AND active = '1'

#expansion_limit = 100

vi /etc/postfix/sql/mysql_virtual_alias_domain_mailbox_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query = SELECT maildir FROM mailbox,alias_domain WHERE alias_domain.alias_domain = '%d' and mailbox.username = CONCAT('%u', '@', alias_domain.target_domain) AND mailbox.active = 1 AND alias_domain.active='1'

vi /etc/postfix/sql/mysql_virtual_mailbox_limit_maps.cf

内容:

user = postfix

password = postfix_password

hosts = localhost

dbname = postfix

query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1'

dovecot与postfixadmin整合

按如下修改或添加:

default_mail_env = maildir:/var/mail/vmail/%u/

 

auth default {

  mechanisms plain

  userdb sql {

    # Path for SQL configuration file, see doc/dovecot-sql-example.conf

    args = /etc/dovecot-mysql.conf

  }

  passdb sql {

    # Path for SQL configuration file, see doc/dovecot-sql-example.conf

    args = /etc/dovecot-mysql.conf

  }

}

 

# Valid UID range for users, defaults to 500 and above.

first_valid_uid = 1001  # Change this to your postfix UID

 

## IMAP quota

protocol imap {

  mail_plugins = quota imap_quota

}

 

## POP quota

protocol pop3 {

  mail_plugins = quota

}

 

## Local Delivery Agent

protocol lda {

  mail_plugins = quota

}

 

## Dictionary DB proxy

dict {

  quota = mysql:/etc/dovecot-dict-quota.conf

}

 

## Default quota values

plugin {

quota = dict:storage=200000 proxy::quota

}

以下两个文件注意修改postfix_password。

vi /etc/dovecot-mysql.conf

内容:

connect = host=localhost dbname=postfix user=postfix password=postfix_password

driver = mysql

 

# Default password scheme.

# depends on your $CONF['encrypt'] setting:

# md5crypt  -> MD5-CRYPT

# md5       -> PLAIN-MD5

# cleartext -> PLAIN

default_pass_scheme = MD5-CRYPT

 

# Query to retrieve password. user can be used to retrieve username in other

# formats also.

 

password_query = SELECT username AS user,password FROM mailbox WHERE username = '%u' AND active='1'

 

# Query to retrieve user information.

 

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'

vi /etc/dovecot-dict-quota.conf

内容:

driver = mysql

connect = host=localhost dbname=postfix user=postfix password=postfix_password

default_pass_scheme = MD5-CRYPT

table = quota

select_field = current

where_field = path

username_field = username

启动服务

postmap /etc/aliases

/usr/sbin/postfix start

service dovecot start

roundcube安装

cd /tmp

wget http://voxel.dl.sourceforge.net/project/roundcubemail/roundcubemail/0.7.2/roundcubemail-0.7.2.tar.gz

tar xzf roundcubemail-0.7.2.tar.gz  -C /var/www/html

mv /var/www/html/roundcubemail-0.7.2 /var/www/html/webmail

mysql -uroot -p

mysql> CREATE DATABASE roundcubemail;

mysql> GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost IDENTIFIED BY 'password';

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。
