76 myhostname = westos.com ###指定mta主机名称
83 mydomain = westos.com ###指定mta域名
99 myorigin = $mydomain ###指定邮件来源结尾
116 inet_interfaces = all ###25端口开启的网络接口
164 mydestination = $myhostname, $mydomain, localhost ###指定接受的邮件结尾
systemctl restart postfix.service
systemctl stop firewalld
测试
在westos.com端给mmm.com发邮件
在mmm.com端查看
3.邮件别名
在接受邮件的主机配置
vim /etc/aliasses
别名: 真名
别名： ：include：filename ###邮件群发
vim filename
root
student
postalias /etc/aliases ###更新aliases文件
测试
在发送邮件端
在接收邮件端
