This simple SMTP server scanning tool allows you to test a list of SMTP servers for connectivity. It checks whether a connection can be established using the provided credentials and saves the details of live SMTP servers to a file.

This script reads email addresses from emails.txt, attempts to verify each address by: (1) checking basic syntax, (2) resolving the domain's MX record via dnspython and (3) attempting an SMTP handshake to see if the mail server will accept the recipient.
