worst cases of emails I have gotten are from Sony. For example, Planetside 2 beta acceptance letter came from info@e-sonyonline.com and without ANY personal information. It was the most generic official letter I have received. Link to download PS2 was also from link.e-sonyonline.com. I disregarded it first, only after a while, discovering it was genuine. And a lot of people are having doubts about this aadress, just google it.

Also, their password reset letter comes from something like contact@p7s1games.net. I usually disregard everything like this automatically. Luckily reset link is planetside2.eu.
