56129 E-Mail Extractor

Need a crawler to do the following 1. Start from a seed URL and follow links found 2. Extract Title, URL and E-mail address from visited site if certain kewords are found on the site. I will define the keywords to look for. 3. Send a mail to the Email address found 4. Store the data (Title, URL and Email) for future use. I should be able to start and stop the crawler and I need to ensure that I don't send duplicate mails to the same place. I am also open to suggestions. As handsfree as possible. no encryption please, Thank you
