Yes. The email is pointing to a site that is not mt.gox.

What do you mean? There are no links there...
Mt. Gox's site DOES say you can't access it from the Tor network and that they might take extra verification measures if you do try it.
Have you been using Tor? If so, maybe it's legit (I don't use Tor so I've never seen what they do)
In any case, as long as you go straight to mtgox.com and ensure it is a secure connection (green in the address bar) and don't click on links in an e-mail you should be fine.
