There is a program that, upon registration, issues recovery keys. I made it possible to save to a file on a computer and you need to implement the ability to send it to the mail. I found many examples and libs for sending, but everywhere you need to enter the sender's address and password. And I need without the sender's address. type of robot.

Raise the service on your server, a request from the program will come there, and already send a letter from the server.
