A bigger question might be, who sent it? Was it really the person you claim it is?
It's easy to show the receipt of an email and where it came from (especially when you have full headers). But unless the sender bothers to GPG or S/MIME sign the email, in theory, it could have been sent by another person who had access to the account. Or, it could have been spoofed, etc.
