You could get your firewall ACCEPT but LOG the outgoing 25 from anything
but your mailhub.
Have often wondered whether a transparent mail-proxy could be set up,
similar to a transparent web-proxy, with your firewall catching all port
80 and redirecting to 8080 on your squid server. Never got around to
seeing whether this was possible ...
... then again I agree with the others, blocking outgoing port 25 is the
better idea, but only if it is not going to get you fired.
