I'm talking about 8000-10000 domains. I'm not familiar with perl. Is there a program that can do this?You can whois all of the popular domains through command line. The fastest way would be to download a registry list of all the .com's and then use Perl to whois all of them and output the results to a file. You could then simply extract the emails from that file. If you're planning on scraping millions of domains, this would be the fastest way.
