1,Extmail概述
ExtMail Solution 是一个基于优秀开源软件的电子邮件系统解决方案,核心部件包括了Postfix、Amavisd-new、ClamAV、ExtMail、ExtMan、Courier系列软件。是一个功能相对比较齐全的免费电子邮件系统。
而其中Extmail 是一个以perl语言编写,面向大容量/ISP级应用,免费的高性能Webmail软件,主要包括ExtMail、Extman两个部分的程序套件。ExtMail套件用于提供从浏览器中登录、使用邮件系统的Web操作界面,而Extman套件用于提供从浏览器中管理邮件系统的Web操作界面。
2,Extmail工作原理
Extmail的核心部分是postfix,是一种web页面,可以创建账号,可以收发邮件。extman可以账号注册。账号存放在mysql里面。postfix发信件,dovecot收信件。利用outlook收信件(docecot)和发信件(postfix)都要通过mysql查询。发信件(postfix)要提取mysql账号信息要通过courier-authlib。是基于虚拟帐号的邮件系统。
配置准备:
修改主机名为mail.aolens.cn
在DNS上解析mail.aolens.cn
@ MX mail.aolens.cn
mail A ip地址
3,Extmail搭建
3.1 安装依赖

postfix版本:postfix-3.2-20160327

#创建sysv脚本
[[email protected] /media/postfix2.6/etc/rc.d/init.d]# cp -p postfix /etc/init.d/ [[email protected] ~]# chown -R postfix /var/lib/postfix [[email protected] ~]# service postfix start 启动 postfix: [确定] [[email protected] ~]# ss -tnlp|grep 25 LISTEN 0 100 *:25 *:* users:(("master",55347,13)) [[email protected] ~]# chkconfig --add postfix [[email protected] ~]# chkconfig postfix on [[email protected] ~]# vim /etc/postfix/main.cf #添加下列参数 myhostname = mail.aolens.cn mydomain = aolens.cn myorigin = aolens.cn #邮件地址伪装伪装mail.aolens.cn为aolens.cn inet_interfaces = all mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain #所有目标邮件为以上的就是本机,不用中继了 mynetworks = 192.168.1.0/24,127.0.0.0/8
##这里注意一下,我192.168.1.0/24开始的时候写成192.168.1.129/24 导致rcpt to:.. 一直453错误。
使用以下命令验正postfix是否支持cyrus风格的sasl认证,如果您的输出为以下结果,则是支持的:
[[email protected] ~]# service saslauthd start 正在启动 saslauthd: [确定] [[email protected] ~]# postconf -a cyrus dovecot
postconf命令:配置postfix
-d:显示默认的配置
-n:显示修改的配置
-m:显示所有所支持的查找表类型
-a:显示支持的SASL客户端插件类型
-e:PARMATER=VALUE:更改某参数配置信息,并保存至main.cf文件中
smtp状态码:
1XX:
2XX:正确信息
3XX:当前信息没有结束
4XX:暂时性错误
5XX:永久性错误
smtp:协议命令
helo (smtp协议)
ehlo (esmtp协议)
mail from: 邮件发送人
rcpt to: 邮件接收人
date 邮件内容
Subject: 邮件标题
. 邮件结束符
alias:邮件别名
[email protected]:[email protected] 法网abc的其实会发到efg
使用newaliases来生成/etc/aliases.db
验证postfix是否安装OK
[[email protected] ~]# useradd test [[email protected] ~]# telnet localhost 25 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost.

我们发现在邮件投递目录里对应的用户中有我们发送过来的邮件。这就说明发送成功了
