Isn't this how pretty much any mail client does it? Thunderbird does a decent job at spam filtering my mail. You know, I can even search folders in Outlook! Saying that scanning your 1M mails with 1kb each requires the use of a cloud service seems a bit over the top.

And how long does that search take? How long does it take to download that mail to a new device? How long would that have been on 2006 Internet? I've never said that it's impossible. I've only said that it takes away the main advantage claimed at launch — fast, working search.
