Contacts Verifier is the first add-in for Microsoft Outlook 2000, 2002/XP and 2003; designed to monitor the validity of e-mail addresses in your contacts. It is able to check your address-book throughout in a matter of minutes notifying you of contacts that contain e-mail addresses which are no longer valid. Contacts Verifier is also operable in mail merge mode with Microsoft Outlook 2002 and Microsoft Word 2002, as well as with the newer version 2003. It checks e-mail addresses from an address source used for mass mailing and excludes invalid addresses. When checking an address, CV imitates the sending of the message to the address being checked, and after receiving the answer from the server (to which the address belongs) as to whether the address exists or not, it terminates message sending and ends the session correctly. So, the checking of an address is technically correct and cannot be noticed by the address owner. Contacts Verifer supports Socks5 protocol and NAT to work in LAN, fast multithread verifying, and has a comfortabe user interface. Information is becoming more and more valuable in our rapidly changing world, and we hope you will find our software product useful and easy to deal with.
