Why wouldn't you receive a legitimate e-mail from a proxy server? I have several customers who have their mail servers on the same server as the proxy server. And then there is the case of the mail server being behind the proxy server and it's address is being translated so that it looks like it's coming from the proxy server. What is it that you want Davide to do?
