DomainToEmailAddress Whois

From Paterva Wiki

This transform performs a recursive whois query on the supplied domain and parses the output for email addresses. The idea with the transform is to provide the email address of the owner of the domain. The whois information itself is stored as a property of the domain ('Domain Whois'). You should always manually inspect this data to give context to results - or see if the parsing of the email address failed. For more information about whois see the Wikipedia entry here [1].
