Objective :
The objective of this project is to validate an email address from the side of SMTP server, without really sending a message to given email. If -by sending a series of SMTP commands- an email is acknowledged by its SMTP server, then it is an "valid" email.
Processes :
1. Fetch domain name of the email
2. Verify the domain
3. If its verified, send some SMTP commands
4. Based on its responses, we take an "educated guess" about the status of a given email
