Advanced Email Verifier

Advanced Email Verifier - description from Softdepia.com:

Advanced Email Verifier is designed for system administrators, webmasters, programmers as well as for those advanced users who have their own mailing lists and would like to keep them up-to-date. Advanced Email Verifier verifies every email address from a given mailing list, allows to determine about 90 % of dead mail addresses. You don't need to disturb your clients and friends anymore to check if their e-mail addresses are still valid. Advanced Email Verifier connects directly to their SMTP server and checks it for you. Nothing is sent to the recipient. Advanced Email Verifier helps to decrease Internet traffic, because you can "wash" your mailing list beforehand, avoiding sending undeliverable messages that cause a ping-pong of useless messages between SMTP servers. As well as saving your Internet resources, Advanced Email Verifier helps you to save money. AEV supports import from Windows Address Book (.WAB) as well as through ODBC SQL to allow to get e-mail addresses from external sources.

Advanced Email Verifier has the following features:

• Instant verifying of bad email addresses and invalid domains.
