Using Python to execute system commands via mail

Implementation of the idea: by detecting the inbox of the mail sent by the specified user, detect the message header, execute the specified command. The program periodically detects messages in the Inbox, separates the sender and title of the first message in the Inbox, ignores the message if the sender is not the specified user, detects the title in the message and executes the specified command in the header, and sends two messages out, a message with a meaningless title to itself, Prevents repeated execution of a command, sending a message to a specified user informing the user that the corresponding command has been executed.
