Matt Mullenweg has a few e-mail goodies that no one has… yet:

So the long and short of it is, I’m loading all the email I receive into a database using a fun combination of Procmail, Spam Assassin, and a sprinkling of command line PHP. I’m very excited about this, more excited than I’ve been about a new project in a while. For me, email has been steadily waning in utility for the past year, and I want to breathe new life into it. I’m tired of folders. I’m tired of slow searching. I don’t want to hand my email over to someone else, even if it’s Google. I don’t want to deal with mbox or IMAP or maildir or any of that junk. Those are implementation details of various servers and clients.

[...] I want to hear your wildest dreams. Besides the obvious search, backup, and statistics benefits, what can you imagine this system doing? What would you like email to address? (groan…) What email metadata is interesting? (I’m currently tracking subject, date sent, date received, from, the message itself, and spam status.) What statistics would be interesting to you? Is anyone even interested in this or am I just spinning my wheels?

I like. I want. But who, then, would build the application for it? Or better yet, what web-based mail apps that exist in my control panel would work with it?
