ubuntu使用mailx發送郵件

關閉sendmail或者postfix

service sendmail stop 

service postfix stop

1、安裝heirloom-mailx

apt install heirloom-mailx

2、配置外部SMTP

我的ECS是Ubuntu16.04 ,配置文件爲/etc/s-nail.rc，把下面幾行放置在最後

如果不配置端口發送可以使用

[html] view plain copy

set from=[e-mail]
set smtp=smtp.163.com
set smtp-auth-user=[e-mail]
set smtp-auth-password=123456
set smtp-auth=login

如果配置端口則

[html] view plain copy

set from="[e-mail]"
set smtp="smtps://smtp.163.com:465"
set smtp-auth-user="[e-mail]"
set smtp-auth-password="123456"
set smtp-auth=login

或者

[html] view plain copy

set from="[e-mail]"
set smtp="smtps://smtp.163.com:465"
set smtp-auth-user="[e-mail]"
set smtp-auth-password="123456"
set smtp-auth=login

注：以上三種配置都可以嘗試

3、發送

echo 'this is test' | mail -s "test email." [email protected]
