Arclab MailList Verifier

MailList Verifier checks email addresses for validity. You can use the program to clean up your mailing lists and get rid of non-existing email addresses. Its easy to use and supports multi-threading for fast processing.

The program works the same way as a mailserver does. It retrieves the mail exchanger for any email address and tries to connect to the mailserver, which accepts incoming messages for the given email address.

It simulates sending a message, but does NOT send any message. The program disconnects as soons as the mail server says the email address exists or not.
