postfix负责发信，dovecot负责收信（imap和pop3），一起完美构成邮件服务器。

我们使用MariaDB作为postfix用户和域名的数据依赖。现在连接并创建新数据库。

mysql -uroot -p
CREATE DATABASE postfix;
CREATE USER 'postfix'@'localhost' IDENTIFIED BY 'PApassword';
GRANT ALL PRIVILEGES ON postfix.* TO 'postfix'@'localhost';
FLUSH PRIVILEGES;
QUIT;

安装postfix admin后台管理页面

cd /usr/local/src
wget http://downloads.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin-2.93/postfixadmin-2.93.tar.gz
tar zvxf postfixadmin-2.93.tar.gz
rm -rf /var/www/html/postfixadmin 
mv postfixadmin-2.93 /var/www/html/postfixadmin
chown -R nginx:nginx /var/www/html/postfixadmin

编辑配置文件

vim /var/www/html/postfixadmin/config.inc.php

按下面修改

<?php
$CONF['configured'] = true;

$CONF['database_type'] = 'mysqli';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = 'PApassword';
$CONF['database_name'] = 'postfix';
?>

创建session文件夹并赋予权限

mkdir /var/lib/php/session/
chown -R nginx:nginx /var/lib/php/session/

postfix admin后台设置

现在可以打开https://postfixadmin.mydomain.com/setup.php，点击忘记setup password的忘记密码，输入自己想要的密码，会得到一段hash值，复制到/var/www/html/postfixadmin/config.inc.php第30行

$CONF['setup_password'] = '82020bc067e2a6deaa3fba3632529114:0834f649bf09ee930910ab1b353e3f0722b77ee8';

这样就可以登录，登录后可以创建域名和用户

https://postfixadmin.mydomain.com/users/login.php这是普通用户的登录地址。

BUG修复

在后台点击Fetch email会出现错误，打开/var/www/html/postfixadmin/model/PFAHandler.php572行，修改

$base64_decode = "###KEY###";

连接postfix到MariaDB

创建5个配置文件，复制代码

vim /etc/postfix/mysql-virtual_domains_maps.cf

hosts = localhost
user = postfix
password = PApassword
dbname = postfix
query = SELECT domain FROM domain WHERE domain='%s' AND backupmx = '0' AND active = '1'

vim /etc/postfix/mysql-relay_domains_maps.cf

hosts = localhost
user = postfix
password = PApassword
dbname = postfix
query = SELECT domain FROM domain WHERE domain='%s' and backupmx = '1'

vim /etc/postfix/mysql-virtual_mailbox_maps.cf

hosts = localhost
user = postfix
password = PApassword
dbname = postfix
query = SELECT maildir FROM mailbox WHERE username='%s' AND active = '1'

vim /etc/postfix/mysql-virtual_mailbox_limit_maps.cf
