Whois E-mail Extractor

What I need is a program made that will do whois requests on a list of domain names that come from a text file. I need the program to extract the e-mail addresses on the result page of the whois request. This extractor will need to be multi-threaded and work fast and error free for long periods of time. I want to be able to run this thing all night long. The e-mail addresses need to be saved to a text file as they are found. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Win 98,XP,2000
