Postfix和Dovecot配置Mysql虚拟用户
作者：互联网
安装：
| 1 |
yum install dovecot-mysql
|
新建数据库：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 |
CREATE DATABASE mailserver;
GRANT SELECT ON mailserver.* TO 'mailuser'@'127.0.0.1' IDENTIFIED BY 'mailuserpass';
FLUSH PRIVILEGES;
USE mailserver;
#虚拟域表
CREATE TABLE `virtual_domains` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(50) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
#虚拟用户表
CREATE TABLE `virtual_users` (
`id` int(11) NOT NULL auto_increment,
`domain_id` int(11) NOT NULL,
`password` varchar(106) NOT NULL,
`email` varchar(100) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `email` (`email`),
FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
#虚拟用户别名
CREATE TABLE `virtual_aliases` (
`id` int(11) NOT NULL auto_increment,
`domain_id` int(11) NOT NULL,
`source` varchar(100) NOT NULL,
`destination` varchar(100) NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
添加测试数据：
INSERT INTO `mailserver`.`virtual_domains`
(`name`)
VALUES
('haiyun.me');
INSERT INTO `mailserver`.`virtual_users`
(`domain_id`, `password` , `email`)
VALUES
('1', ENCRYPT('password', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))), 'user@haiyun.me');
INSERT INTO `mailserver`.`virtual_aliases`
(`domain_id`, `source`, `destination`)
VALUES
('1', 'alias@haiyun.me', 'user@haiyun.me');

Postfix添加以下配置：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf
#使用dovecot lmtp交付虚拟域邮件，省却postfix配置用户邮件目录及权限问题
virtual_transport = lmtp:unix:private/dovecot-lmtp
#使用dovecot验证，后面dovecot配置
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination
|
配置Postfix支持Mysql查询表：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
#虚拟域
/etc/postfix/mysql-virtual-mailbox-domains.cf
user = mailuser
password = mailuserpass
hosts = 127.0.0.1
dbname = mailserver
query = SELECT 1 FROM virtual_domains WHERE name='%s'
#虚拟用户
/etc/postfix/mysql-virtual-mailbox-maps.cf
user = mailuser
password = mailuserpass
hosts = 127.0.0.1
dbname = mailserver
query = SELECT 1 FROM virtual_users WHERE email='%s'
#虚拟别名
/etc/postfix/mysql-virtual-alias-maps.cf
user = mailuser
password = mailuserpass
hosts = 127.0.0.1
dbname = mailserver
query = SELECT destination FROM virtual_aliases WHERE source='%s'
|
测试查询：
| 1 2 3 |
postmap -q haiyun.me mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
postmap -q user@haiyun.me mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
postmap -q alias@haiyun.me mysql:/etc/postfix/mysql-virtual-alias-maps.cf

Dovecot配置：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 |
/etc/dovecot/conf.d/10-mail.conf
mail_location = maildir:/var/mail/vhosts/%d/%n
/etc/dovecot/conf.d/10-auth.conf
auth_verbose = yes # 认证详细日志
auth_debug = yes # 认证debug
disable_plaintext_auth = no #开启明文验证
auth_mechanisms = plain login #支持验证方法
#!include auth-system.conf.ext #取消默认系统验证
!include auth-sql.conf.ext #使用mysql验证
/etc/dovecot/conf.d/auth-sql.conf.ext
#用户验证
passdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf.ext
}
#用户邮箱目录 %d为domain，%n为user
userdb {
driver = static
args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n
}
/etc/dovecot/dovecot-sql.conf.ext
driver = mysql
connect = host=127.0.0.1 dbname=mailserver user=mailuser password=mailuserpass
default_pass_scheme = SHA512-CRYPT
password_query = SELECT email as user, password FROM virtual_users WHERE email='%u';
/etc/dovecot/conf.d/10-master.conf
#lmtp服务，postfix通过lmtp交付邮件
service lmtp {
unix_listener /var/spool/postfix/private/dovecot-lmtp {
mode = 0600
user = postfix
group = postfix
}
}
#验证服务，postfix也通过此验证用户
service auth {
unix_listener /var/spool/postfix/private/auth {
mode = 0666
user = postfix
group = postfix
}
unix_listener auth-userdb {
mode = 0600
user = vmail
#group =
}
user = dovecot
}
service auth-worker {
user = vmail
}
|
新建用户用以访问邮件目录数据：
| 1 2 |
useradd -M -u 5000 vmail -d /var/mail -s /sbin/nologin
chown -R vmail:vmail /var/mail/
