Emailserver detector is a program designed to directly search email addresses from mail servers. It can verify all user names that you specified on the mail server.

The program tries to connect with a special Smtp-server and simulates sending the message. It disconnects as soon as the mail server informs you if the address exists or not.

The program is multi-threaded , provides high speed verification and can regulate network traffic and the speed at which your machine loads. It can also send messages to valid email addresses while searching.
