Asp.Net Mass eMails Checker is a smart & simple & easy-use web app that allows you to verify email addresses without storing anything in any databases. It extracts the MX records from the email address and connects to the mail server (over SMTP and
also simulates sending a message) to make sure the mailbox really exists
for that user/address.
**Some mail servers do not cooperate the verification process with the
MX records, in such cases, the result of this email verification tool
may not be as accurate as expected (1% error margin).
