How Email Verification Works:

This tool simulates a connection to the recipient's mail server using SMTP protocols to check if the mailbox exists, without actually sending an email. The verification process includes:

1. Finding the recipient's mail server (MX record lookup)
2. Establishing a connection to the mail server
3. Initiating a fake email sending process
4. Checking server responses to determine email validity
5. Terminating connection without sending actual email
