MailList Validator 2.0   
by Business Software Products   

MailList Validator is designed to validate e-mail addresses and see whether or not certain addresses exist. The program's main objective is finding invalid e-mail addresses. This will save a great deal of your time when doing mailings and minimize the number of bounced messages from non-existing addresses. Mail List Validator uses Rules for determining bad e-mail addresses. This allows you to achieve very high accuracy of validation. The program is capable of finding all invalid addresses in a list, and is virtually free of false trigger instances (where a valid address might be marked as invalid.)
