Webmaster Email Extractor is a small yet powerful tool that enables you to collect very valuable information about any domain name that you want by extracting the results from global WHOIS servers worldwide. The program is able to retrieve domain details, such as creation and expiration date, and the domain owner's details, such as name, address, phone, fax and email. These data are very useful if you are going to advertise for a product that the owners of these websites find convenient. The program can export only the administrators' email addresses, domain name and, reduced domain information or complete information. You can add more WHOIS servers by editing the WebmasterEmailExtractor.ini file. The number of threads and the timeout value can be configured from the program's options. When the program detects that you were banned from a WHOIS server, it will slow down the request interval to reduce the probability of being banned from other WHOIS servers as most of them place protection mechanisms against automated requests. This is why the program is firewall friendly and supports connecting through socks4 and socks5 proxies.
