This reminds me a lot of the server-side procmail [0] and Sieve filters [1]. Perhaps this was even the inspiration for such a project, who knows? But tray.io looks like it can handle far more advanced rules (or at least those somewhat comparable to procmail, and without having to do a bunch of manual scripting!), but in a more user-friendly, graphical way. And if it can automatically generate machine-learned rule suggestions based on user behavior, that would be even more fantastic. The only major downside is that you have to be willing to let a third-party have access to your e-mail (and I know that when I've written server-side procmail scripts that have misbehaved, I've managed to unintentionally lose e-mail at least once or twice in my lifetime; of course, I didn't know that I had even lost the mail, since the server silently discarded it due to my malformed rules).
