How to verify an email's sender identity?

How to verify an email's sender identity?

I just got an email from a company whom I'd really like to work for, but I am not convinced that the person emailing me is real, or a hoax. Is there a way based on the MIME information and all the email headers to heuristically determine if an email came from who it says it came from?
Update
Thanks to everyone for the great answers, I figured there was no one great way to tell. I checked the MX records on the DNS servers and the WHOIS records for the domains and IP addresses and it all checked out. Just for some context, I was contacted first on LinkedIn, so it wasn't totally out of the blue.
