Extmail + Postfix on Debian5

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）

导入Extmail数据库
mysql -uroot -p"ROOTPWD" < /var/www/extman/docs/extmail.sql
mysql -uroot -p"ROOTPWD" &lt; /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
&lt;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

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/
find ./ -name 'mysql_virtual_*' -exec sed --in-place 's/localhost/127.0.0.1/g' {} \;
修改 main.cf 文件

    reject_unknown_recipient_domain,
    reject_unauth_destination,
    reject_unauth_pipelining,
    reject_invalid_hostname,
    check_recipient_maps
修改master.cf 文件
vim /etc/postfix/master.cf
smtp      inet  n       -       -       -       -       smtpd
改为
smtp      inet  n       -       n       -       -       smtpd
.和
maildrop  unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient}
改为
maildrop  unix  -       n       n       -       -       pipe
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
vim /etc/courier/authmysqlrc

创建/etc/postfix/sasl/smtpd.conf 加入下面的内容 
vim /etc/postfix/sasl/smtpd.conf
pwcheck_method:authdaemond
log_level:0
mech_list:PLAIN LOGIN
allow_plaintext: true
authdaemond_path:/var/run/courier/authdaemon/socket

图形日志配置

修改mailgraph-init
vim /usr/local/mailgraph_ext/mailgraph-init
MAIL_LOG=/var/log/maillog
改成
MAIL_LOG=/var/log/mail.log

添加自动执行计划
sudo crontab -e
30 4 * * * /var/www/extman/tools/reportusage.pl -all /home/domains [email protected]
添加开机自启动项
vim /etc/rc.local
/usr/local/mailgraph_ext/mailgraph-init start
/var/www/extman/daemon/cmdserver -v -d
/usr/bin/rsync --daemon
chmod -R +x /var/run/courier/authdaemon
