How works the process of verifying Email?

• The process of verifying email is done by sending SMTP HELLO command to other side (SMTP server) asking to verify email address.
  Once SMTP server accept our request and our "question" then he let us know of Mail ID / Recipient is OK or NOT.
• Final step of our email lookup process is to let you show answer from SMTP server after the process of verification and checking has been done:
  "the host states that the address is valid or not."
  
  Once we get answer we disconnect from SMTP server.
