Extmail + Postfix on Debian

概述：

操作系统采用Debian5 GNU/LINUX，MTA主程序使用Postfix，MDA为Courier+Maildrop，使用MySQL作为账户数据库，后台邮件账号管理系统使用Extman，前台用户Webmail使用Extmail。该系统所有使用的软件（除extman和extmail以外）均采用Debian软件包库自带软件，使用aptitude install安装所需软件。

目标：该邮件系统可以满足最简单的中小企业邮件系统的需求，提供如下服务

1、带密码验证的SMTP发件服务

2、带密码验证的POP3收件服务

3、支持多虚拟邮件域和邮箱配额管理

4、用户可通过WEB页面，管理收发邮件

5、邮件管理员可通过WEB后台管理系统，管理邮件账号和虚拟邮件域

安装与配置步骤：

一、系统安装
系统最小安装
安装过程中需新建普通账户，账号名为：extmail （下面的配置可以自己采用此账号）

系统重启后需先安装openssh-server，以方便可以SSH远程管理和配置系统

aptitude install openssh-server
二、基本软件安装（出现提示，直接按默认配置）
aptitude install mysql-server postfix-mysql courier-authlib-mysql courier-pop libsasl2-modules-sql maildrop apache2-suexec-custom libunix-syslog-perl mailgraph

三、下载并配置 Extmail（用户webmail系统） + Extman（管理员后台系统）
1、下载好的最新的 Extmail 和 Extman 软件包，版本如下
extmail-1.2.tar.gz
extman-1.1.tar.gz

2、解压并设置相关目录
tar -zxvf extman-1.1.tar.gz
tar -zxvf extmail-1.2.tar.gz
cp -R extmail-1.2 /var/www/extmail
cp -R extman-1.1 /var/www/extman
mkdir /home/domains/
chown -R 1000:1000 /home/domains
chown -R 1000:1000 /var/www/extmail/cgi/
chown -R 1000:1000 /var/www/extman/cgi/
#说明：上面的1000为系统安装时创建的extmail账户UID和GID，因为下面的Extmail和Extman里的配置文件均需这个系统账户

3、设置 Extmail & Extman 配置文件
修改Extman配置文件如下（可参考webman.cf.default）
vim /var/www/extman/webman.cf

导入Extmail数据库
mysql -uroot -p"ROOTPWD" < /var/www/extman/docs/extmail.sql
mysql -uroot -p"ROOTPWD" < /var/www/extman/docs/init.sql
cd /etc/apache2/mods-enabled/
ln -s ../mods-available/suexec.load ./suexec.load
cd /etc/apache2/sites-enabled/
rm -rf /etc/apache2/sites-enabled/000-default

创建extmail虚拟服务器文件，内容如下
vim /etc/apache2/sites-enabled/extmail
<VirtualHost *:80>
ServerName mail.ruirong.org
DocumentRoot /var/www/extmail/html/

ScriptAlias /extmail/cgi/ /var/www/extmail/cgi/
Alias /extmail /var/www/extmail/html/

ScriptAlias /extman/cgi/ /var/www/extman/cgi/
Alias /extman /var/www/extman/html/

# Suexec config
SuexecUserGroup extmail extmail
</VirtualHost>
四、配置postfix & courier 与 extmail & mysql 连接

使用mysql作为postfix的后台数据库
cd /var/www/extman/docs/
cp mysql_virtual_*.cf /etc/postfix/
chmod o= /etc/postfix/mysql_virtual_*.cf
chgrp postfix /etc/postfix/mysql_virtual_*.cf
cd /etc/postfix/

修改master.cf 文件
vim /etc/postfix/master.cf
smtp      inet n       -       -       -       -       smtpd
改为

flags=DRhu user=extmail argv=/usr/bin/maildrop -d ${recipient}
配置courier
cp /etc/courier/authdaemonrc /etc/courier/authdaemonrc.bak
vim /etc/courier/authdaemonrc
authmodulelist="authpam"
改为
authmodulelist="authmysql"

mv /etc/courier/authmysqlrc /etc/courier/authmysqlrc.bak
