This is a Email Account Checker that I made in C#. It's 100% accurate literally no joke. It's multi-threaded and only supports Gmail and Hotmail. Enjoy!
Note: Must have the .dll and the .exe file together in order for the program to work!
How it works: The program sends a email to a random email using the username and you password that you inputted. If there's no error on sending, then it's working. If there's a error, it's not working. It's using try catch
You should release the source as you wouldnt really use the program on its own as you could just go to thw website and check if your details are correct.
But if we had the source, we could implement it into applications, which require emails to be sent etc.
