My wife has had an increase in SPAM since getting her iPhone. Worse, it seems MobileMe doesn't do spam filtering, or does it very badly, because she gets lots of spam in her iPhone inbox. Weirdly, it seems spam filtering is primarily done client-side, by Apple Mail on the desktop; but when her iMac sleeps that can't happen. So...uhm...is there a hidden toggle in MobileMe that turns on spam filtering? Is Apple still in 1999 with regard to SPAM and expects you to do all processing and filtering client-side, rather than server side? How do you deal with SPAM on your iPhone with MobileMe?
