编译安装postfix2.10邮件服务（linux系统为64位redhat6.0）：
首先下载postfix2.10文章末尾有下载地址；
SMTP:（Simple Mail Transfer Protocol）即简单邮件传输协议
POP3：邮局协议 IMAP4：internet mail access protocol 互联网邮件访问协议
SASL：simple Authentication Secure layer 简单安全认证层 （版本v1,v2目前主流v2版本）
MDA：邮件投递代理（procmail,maildrop）
MUA：邮件用户代理（mutt）
mail relay: 邮件中继
MTA：报文传输代理 （sendmail,postfix,qmail,exim）
Postfix的配置文件：
postfix模块化：
master:/etc/postfix/master.cf 主进程配置文件
mail:/etc/postfix/main.cf 主配置文件(相关配置的主配置文件)
格式：参数 = 值：参数必须写在绝对行首(即行首不能有空格)，以空白开头的行被认
为是上一行的延续(即行首有空白的行都是上一行没有写完的内容)。
postconfig: 可以直接配置修改postfix的主配置文件
-d: 显示默认的配置
-n: 修改了的配置
-m: 显示支持的查找表类型
-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主配置文件中
-a: 服务器端支持的SASL插件类型
smtp状态码：
1xx:纯信息
2xx:正确信息
3xx:上一步操作尚未完成，需要继续补充
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: 指定发件人
rcpt to：指定收件人
data 输入正文
Subject: 邮件主题
邮件正文以.结束

postfix服务启动脚本：可以通过service postfix start|restart

[root@lamp ~]# service postfix restart
关闭 postfix： [确定]
启动 postfix： [确定]
2、进行一些基本配置，测试启动postfix并进行发信。
修改/etc/postfix/main.cf
修改以下几项配置（红色部分）：
myhostname = mail.lamp.com
myorigin =
mydomain =
mydestination =
mynetworks =
说明：
myorigin参数用来指明发件人所在的域名，即做发件地址伪装；
myhostname参数指定运行postfix邮件系统的主机的主机名，默认情况下，其值被设定为本地机器名；
mydomain参数指定自己的域名，默认情况下postfix将myhostname的第一部分删除而作为mydomain的值；
mydestination参数指定postfix接收邮件时收件人的域名，即你的postfix系统要接受到那个域名的邮件
mynetworks参数指定你所在的网络的网络地址，postfix系统根据其值来区别用户是远程的还是本地的，
如果是本地网络用户则允许其访问；
inet_interfaces参数指定postfix系统监听的网络接口；
注意：
1、在postfix的配置文件中，参数行和注释行是不能处在同一行中的；
2、任何一个参数的值都不需要加引号，否则，引号将会被当做参数值的一部分来使用；
3、每修改参数及其值后执行postfix reload即可令其生效，但若修改了inet_interfaces；
则需重新启动postfix；
4、如果一个参数的值有多个，可以将他们放在不同的行中，只需要在其后的每个行前多置一个空格
即可；postfix会把第一个字符为空格或tab的文本行视为上一行的延续；
3、修改主机名
[root@lamp ~]# hostname mail.lamp.com #临时修改主机名，立即生效，重启失效
[root@lamp ~]# hostname
mail.lamp.com
[root@lamp ~]# vim /etc/sysconfig/network #永久生效，修改主机名，重启后生效
NETWORKING=yes
HOSTNAME=mail.lamp.com
[root@mail ~]# hostname
mail.lamp.com
4、安装配置DNS服务器
[root@mail ~]# rpm -qa |grep bind #查看系统是否安装过DNS
PackageKit-device-rebind-0.5.8-13.el6.x86_64
bind-libs-9.7.0-5.P2.el6.x86_64
samba-winbind-clients-3.5.4-68.el6.x86_64
bind-utils-9.7.0-5.P2.el6.x86_64
rpcbind-0.2.0-8.el6.x86_64
[root@mail ~]# rpm -e bind-libs bind-utils #先卸载已经安装的bind
[root@mail ~]# yum install bind.x86_64 bind-libs bind-utils
