SMTP tool for Email validation

Hi,

We are looking for a tool for bulk SMTP testing / Email validation using telnet or similar protocol ( which doesn't send the mails )

It generally involves steps like NSlookup to check MX of destination server, opening port25, telnet to communicate with client server, then finally checking the correctness of user email account.

Please connect if you have such ready tool with you or you can develop

Process example- https://blog.mailtrap.io/verify-email-address-without-sending/ https://blog.mailtrap.io/verify-email-address-without-sending/

Thanks & regards
