Typically, this is not a question that will be answered by Intel's support agents. What I can tell you is:
- 'intel.com' is the legit domain for Intel. Unlikely it can be spoofed.
- The 'x' in the name signifies that this is (or perhaps was) the email address for a contract employee.
As for whether he is a current contract employee is something that can be determined simply by attempting to send him a message. It should bounce back if he is not.
Hope this helps,
