I've been using http://www.buzz.to as a mailto: URL redirect. This way, I can centrally hide/cloak my e-mail address via a link. Along with http://www.sneakemail.com , I can rapidly change the URL to a new email address once it starts receiving spam. (Eventually, e-mail harvesters will get smart enough to harvest addresses from redirects, too, I suspect.) It works great! It seems to be the only URL redirection service that allows mailto: (and not merely http: redirects). P.S. http://www.ef8.net and http://www.tr.cx also seem to allow mailto:. http://homepage.nu may also support this. http://www.myredirector.com seems to support this.
