your could use exim/postfix and route the mail to the right server, but I guess
you are trying to find out how to have port 25 on the real ip nat'ed to one of
the 3 dmz'ed ip based upon the destination mail address
short answer you can't as far as I know, iptables only looks at src ip / src
port & dest ip/dest port. You could write your own plugin module to look into
the tcp stream.
