利用postfix&mailx搭建邮件服务器

1、安装postfix和mailx组件

apk add postfix
apk add mailx

2、按照以下内容修改/etc/postfix/main.cfg，如果参数前面有#注释，请去掉

myhostname = mail.test.com
mydomain = test.com
myorigin = $mydomain
inet_interfaces = all
inet_protocols = ipv4
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
home_mailbox = Maildir/

3、重启postfix

alpine:~# /etc/init.d/postfix start * Caching service dependencies ... [ ok ] * Starting postfix ... 
alpine:~# /etc/init.d/postfix status * status: started [ ok ]

4、测试邮件是否正常发送

echo "test postfix" | mail -s "title" [e-mail]

注：xxx.163.com为自己邮箱地址
5、登录自己邮箱，查看是否收到邮件

6、关闭服务

alpine:~# /etc/init.d/postfix stop * Stopping postfix ... [ ok ]
alpine:~# /etc/init.d/postfix status * status: stopped

7、测试ok
