From the developer:
YL Mail Verifier verifies every e-mail address from a selected database or mailing list, allowing you to determine up to 90% of "dead" mail addresses. After loading your mailing list for a cleanup, YL Mail Verifier starts verifying each email address for validity. All addresses are checked in the multithreaded mode, which speeds up the entire process.
