ECrawl

ECrawl is an email extractor/email harvester that crawls the Web and extracts all the emails it can find. It has the ability to reach speeds in excess of 2 million emails per hour. This is the successor to the very popular email extractor MailCrawl with several new functions and fixes. It also has support for HTTP, HTTPS and SOCKS v5 proxies to keep you anonymous if you so wish. Save a maximum of 5000 emails. ECrawl can run on any connection that can access the Internet, but the faster the better. The search is fully automated and you can add any amount of keywords for it to go through.
