Unknown e-mail

Heya Magulles,

You should always check the email headers of the emails you receive from us, here is some information that can show you how to verify if an email is legit or not.

What should I look for in the header?

Email headers contain information about the sender (who sent the email message), the path the email took to reach your inbox, and things that may have happened to the email before arriving. This information is very important and can be used to determine whether or not an email is malicious.
Once you've accessed an email's header information, you'll want to attempt to verify the sending address. To do this, look at the "Return-Path" or the "originating address" for the email. For most phishing emails, the email address displayed in this location will differ from the address displayed in the "From" field.


A legitimate header from Blizzard Entertainment should look something like this:

X-SID-PRA [email protected]
or
Return-Path: < [email protected] >
Received: from smtp01.worldofwarcraft.com ([XX.XXX.XXX.XXX]) by…
Received: from … by smtp01.worldofwarcraft.com …
for <Your Email Address>; Tue, 29 Jan 2008 10:46:05 GMT
From: [email protected]
To: You’re Email Address


If you believe you've received a phishing email, please forward the email to [email protected] , at your earliest convenience. When forwarding the email, copy and paste the entire email header into the message body to ensure that we are able to identify the source. This information will help us prevent future phishing emails of the same type.
