Forgive my ignorance of iptables since I usually use pf for firewalling,
but I know with pf you can intercept any outbound connection to a
specific port and redirect it to a locally running daemon listening on
another port.  This is how many people do squid transparent proxying. 
That way anything trying to go out to port 25 of a remote host would be
intercepted and redirected to stunnel as described earlier.
