They are getting better and better at this.

This time they were able to get the @blizzard.com

Didn't know they could do that.

Unfortunatly, it's pretty easy to change the email that is sent. When you send an email, it sends a package to the email server. You just have to hack that package and make sure your email adress will be changed, et voila. Next step is using a proxy and happy hunting.

Actually it is even easier. Most email server let you send email from any address, so you could setup an "@blizzard.com" email account on your client and send all the mail that you want. You just can't receive mails.

Yeah, it's getting pretty sad that they go to so much extent, and still show the HTML address typed out wrong...

And again... This time with a nifty background...

These guys really seem to like you.

I give them a B+ for effort, but a C for originality (because they're not SUPPOSED to be original when trying to mimic an official email!!).

In the first image you posted the links in the e-mail it looks like wor1d with a 1 in place of the l. Just my observations.
