@Linkat,
Do you know this person? If not, delete it. It's bad business protocol if it's a legitimate business associate or coworker to have such a vague email (no email company letterheads), no particulars about you (the recipient of the email): name, address, phone number, MOST IMPORTANTLY: no particulars about him (the sender of the email): name, address, phone number.
If it really is authentic and real, he'll resend the email with some verifiable details.
