You'll be greeted with the following message:-
We can’t provide service under the Gmail name in Germany; we’re called Google Mail here instead.
If you’re traveling in Germany, you can access your mail at http://mail.google.com.
Oh, and we’d like to link the URL above, but we’re not allowed to do that either. Bummer.
For general information about Google, please visit www.google.com or www.google.de.
This is likely because Google lost trademark battle with German Daniel Giersch, who owns “G-mail”. Already since some time, German Gmail users will not see a Gmail logo on top – rather, the logo says “Google Mail” – and upon registering, they receive firstname.lastname@example.org instead of @gmail.com.
So for German users, the only change as far as I can tell is they now have to enter mail.google.com instead of gmail.com to get to their inbox. As you can see in Google’s message above, Google isn’t even allowed to link to mail.google.com when you enter the gmail.com domain...
