Hi - I use mobileme just fine on my home wi-fi, but on my university network i can't seem to sync up. The uni network uses a proxy, is that likely the problem?
AFAICT MobileMe Mail on OS X has never supported proxies, and just doesn't work. On iPhone it used to work under 3.X but seems to have broken under 4.0
Sync for contacts and the like works fine, but not mail
