It will prevent relaying from points outside the server, yes, However, be
carefull, if he has ftp access, it could upload a spamware cgi script and
spam from inside the server, that one is really nasty as he has direct
access to a fast connection then...

You could also add his IP as a reject ;)

ps: If you know where he's sending them To , you can sneak in an alias and
grab a few :)

You might also want to alias his address so you ctch the
bounces/complaints, don't let him play too long, or you are gonna get flak
