This is a survey of existing mail to web interfaces. It started as the ISP SPIN needed to implement such a system and had a market research done. Its initial version was done by Ruben Unteregger. All further updates were done by Tomas Pospisek. The page is occassionaly being updated especially upon peoples' requests, but is not being maintained very actively any more. Your feedback is very appreciated. There's a webmail evaluation at University of Pennsylvania.
