This isn't strictly an OSX problem, although is related to it. My company has webmarshall software running, which restricts access to certain sites. Not much of a problem, except that one of the things it does is to ban any sites with "webmail" in the URL. This means that I can't access my .mac mail, which is a pain as I'm often away from home, staying in hotels, and would really like to be able to check my email.
Can anyone suggest any cunning ways around this?
