I agree that this does seem to be a little overkill - the rule seems to
be a little too general. It is true that there are problems with
formmail scripts, but it is not a problem with _all_ formmail scripts,
on all hosting platforms.

Perhaps the question is actually, whether a rule of this nature should
be removed from the general distribution, or removed by the server
administrator? This really depends on the reach of the rules - to be "on
the safe side" it should probably be left in, and removed by an
administrator who feels that their setup is formmail-safe.

Just my £0.02.
