When a visitor has entered their email address to receive information from website owners, is it possible to link an auto-responder email to respond to their submissions? If this is not feasible, than is it possible that site owners are informed of form submissions through their site, by receiving a auto-responder confirmation email? This confirm email could include data that shows the ISP address, date, and time of a visitor's submission as well as pertinent information that reflect the form that was submitted?
Considering the spam laws, it is very possible that authorized submissions could be passed through site owners websites; there is no record to say otherwise. If an auto-responder email system could be implemented for the visitor and the website owner, this would give us a level of security from "possible" spam complaints.
