mailx(mail)配置outlook SMTP方式发送邮件

原文地址：http://blog.51cto.com/wutou/1939117

0x01，环境介绍：

我们用的是微软的邮箱打算用SMTP方式发送邮件。先登录账户看官方给出SMTP信息。

0x02,系统mailx(mail)设置。

通过命令可以看到，mail实际上是mailx的快捷方式。然后在/etc/mail.rc里加入账号等信息。

SMTP加密方式是：STARTTLS

set from=Zabbix使用的发送邮件地址
set smtp=smtp.office365.com
set smtp-auth-user=Zabbix使用的发送邮件地址
set smtp-auth-password=密码
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb/

0x03,创建存放证书的目录

# mkdir -p /etc/pki/nssdb/

0x04,测试mail命令

echo "Zabbix test" | mailx -v -s "test" [email protected]

Zabbix test 要发送的邮件内容，多行内容要写""里。

test 发送邮件的标题。

[email protected] 是对方接收邮件的账号。

0x05,测试执行结果，显示如下说明成功。
