This doesn't address the problem on Unixen that allow one to 'give
away' files.  Nor is it compatible with the philosophy that majordomo
1.x should continue to run under perl4.

The proper fix appears to be simply 'chmod 0750 wrapper', perhaps
along with setting the group owner of wrapper to the same as the MTA.

And, of course, restricting access to the majordomo server.
