**发送邮件

需要安装：postfix
[root@mailwestos named]# #表示服务端
[root@mailwestos named]# #表示客户端

[root@mailwestos named]# vim /etc/postfix/main.cf #主配置文件

76 myhostname = mailwestos.westos.com   #主机名83 mydomain = westos.com        #域名99 myorigin = $mydomain        113 inet_interfaces = all114 #inet_interfaces = $myhostname115 #inet_interfaces = $myhostname, localhost116 #inet_interfaces = localhost117 118 # Enable IPv4, and IPv6 if supported119 inet_protocols = all        #允许所有的端口164 mydestination = $myhostname, $mydomain, localhost

[root@mailwestos named]# systemctl restart named

[root@maillinux Desktop]# vim /etc/postfix/main.cf

76 myhostname = maillinux.linux.com83 mydomain = linux.com99 myorigin = $mydomain        113 inet_interfaces = all114 #inet_interfaces = $myhostname115 #inet_interfaces = $myhostname, localhost116 #inet_interfaces = localhost117 118 # Enable IPv4, and IPv6 if supported119 inet_protocols = all164 mydestination = $myhostname, $mydomain, localhost

[root@maillinux Desktop]# systemctl restart postfix.service

检测：[root@maillinux Desktop]# mail [e-mail]  #发送邮件Subject: AAA      123.EOT[root@maillinux Desktop]# mailq     #邮件队列Mail queue is empty[root@maillinux Desktop]# mail[root@maillinux Desktop]# postqueue -f      #刷新[root@maillinux Desktop]# postsuper -d **   #删除邮件

**本地群发

[root@mailwestos Desktop]# vim /etc/postfix/user #建立群发的群
[root@mailwestos Desktop]# vim /etc/aliases #群发配置文件

.....more:           :include:/etc/postfix/user#more就代表 /etc/postfix/user.....

编辑完 /etc/aliases 文件之后，必须对其加密

[root@mailwestos Desktop]# postalias /etc/aliases #加密
[root@mailwestos Desktop]# systemctl restart postfix.service

测试：[root@mailwestos ~]# mail more  #群发Subject: asdfsadf.EOT[root@mailwestos ~]# mailqMail queue is empty此时便可查看群发的群里面的账户收到邮件信息[root@mailwestos ~]# mail -u username

**域名转换

[root@mailwestos Desktop]# vim /etc/postfix/virtual #域名转换配置文件
You have mail in /var/spool/mail/root

编写格式：[e-mail]         @[e-mail]    [e-mail]假域名             真域名*给 @qq.com 发邮件就等于给 @westos.com 发

编辑完 /etc/postfix/virtual 之后需要对其进行加密

[root@mailwestos Desktop]# postmap /etc/postfix/virtual
[root@mailwestos Desktop]# postconf -d | grep virtual
virtual_alias_maps = $virtual_maps
[root@mailwestos Desktop]# postconf -e “virtual_alias_maps = hash:/etc/postfix/virtual” #用这种方式去读加密文件
[root@maillinux Desktop]# systemctl restart postfix.service

测试：[root@mailwestos Desktop]# mail [e-mail] Subject: BBB111.EOT[root@mailwestos Desktop]# mailqMail queue is empty[root@mailwestos Desktop]# mailMessage 10:From [e-mail]  Tue Mar 14 08:01:47 2017Return-Path: <[e-mail]>X-Original-To: [e-mail]-To: [e-mail]: Tue, 14 Mar 2017 08:01:47 -0400To: [e-mail]: BBBUser-Agent: Heirloom mailx 12.5 7/5/10Content-Type: text/plain; charset=us-asciiFrom: [e-mail] (root)

**伪装

[root@mailwestos Desktop]# vim /etc/named.rfc1912.zones #给需要伪装的域名做解析
You have mail in /var/spool/mail/root

.....zone "qq.com" IN {        type master;        file "qq.com.zone";        allow-update { none; };};.....

[root@mailwestos named]# vim /etc/postfix/generic #伪装的配置文件

.....#将 root@westos 伪装成 [e-mail]@westos.com         [e-mail].....

编辑完 /etc/postfix/generic 之后要对其进行加密

[root@mailwestos named]# postmap /etc/postfix/generic #加密
