Is there any website that is a webapp version of mobile (phone/tablets) apps like k-9 or kaiten etc ?<p>I would love to access a single site and be able to manage all of my inboxes, either combined or separated.
I'm not quite sure what you're asking. Do you want a webmail system that allows you to access multiple email accounts? Or do you want a ready made service that allow you to check various email accounts? I believe both gmail and hotmail will gladly accept your account credentials and check your other email accounts?<p>Or did you want a html5ish web app that stores your email in your browser, and talks to imap and pop3 servers ?
