Python sends e-mail to the specified user via the SMTP service (for Zabbix mail alerts)

The present free mail Service is many, for example 163 enterprise mailbox, QQ Enterprise mailbox and so on. Do not need to build a mail server to send mail to the designated user, only need to register any one of the SMTP protocol support mailbox can be implemented to send mail. Messages can be sent via Linux commands, shell scripts written by themselves, or Python scripts written in Python.

The following code is a simple but practical example. By default, when no parameters are executed, a preset message subject and message content is sent to the preset user. Sends the specified subject and message content to the specified user when the parameter is executed. With parameter execution can be used for Zabbix mail alert scripts.

For zabbix2.x you can fill in the script name directly. For zabbix3.x, you need to specify a parameter, the first is parameter 1, the second is parameter 2, and so on.
