Re: Protection against fake mails

If we a do a google search for the following string "Send free,
anonymous and easy fake email", one of the sites we get is
'deadfake.com'...and many others. I can send an email to myself from
myself by filling in the two fields at the website.
Technically, what such sites seems to be doing is that, such mailers add
an X-Mailer attribute to the message header indicating the message
origin, and an X-Originating-Ip (a real one).
How do I guard against such emails originating from fake email
impersonations. Is there something I can do at our email gateway, proxy
or exchange sever (2003) levels?
As an aside, what a great spam target collection tool.
