Or it isn't being sent as a proper attachment due to error on his or his email client's part, or he's sending one from the Dom3 beta, or Space Empires, or a file from Minesweeper.
Hard for anyone to really say, since due to the anonymous nature of the game you can't actually tell us what you received.
If you look at the raw data of the email message, it
should have something akin to this (my pretender file for Undead game, emailed to myself):
Code:
--Message-Boundary-1026
Content-type: text/plain; charset=US-ASCII
Content-disposition: inline
Content-description: Attachment information.
The following section of this message contains a file attachment
prepared for transmission using the Internet MIME message format.
If you are using Pegasus Mail, or any other MIME-compliant system,
you should be able to save it or view it from within your mailer.
If you cannot, please ask your system administrator for assistance.
