Email w/attachment - Web Interview - Question please?
I received an email and need to know how to verify if the source is legitimate.  Yahoo is unable to do this for me.  I am unable to send a reply, as they will not respond to correspondence. When I did reply, I got no response.
There is an attachment to a web interview system - "corporateoverview.com" . I am not certain this is for real, since I cannot verify the originating source.  
If this is all trusting, I need to get in on the web interview.  I just cannot seem to verify the source, and do not want to expose myself to a scam.  Even the sender's return address is ---@247interview.com.  Just seems a bit fishy to me.
I have attempted to research the person (Mr. Vice Pres.) who sent the email, as well as the interviewing system company, but have had no luck.  
Any tricks to detecting a phony email by viewing headers or whatever?  
Your advice would be greatly appreciated.  Thank you.
islandprince: Can you please tell me how you find out whether or not the source is registered? thanks.
