Yes, letting execution of ifmail and ifnews to anybody is dangerous on a
multi-user system, as they can by passing the right parameters, force ifcico
to do outgoing calls. That can cost the sysop a lot of money.

I use :

MODE = 0711
SMODE = 4710

Then I add user "fnet" to the "news" group in /etc/group
(fnet being of the uucp group) and I add "U=fnet:uucp" to the definition
of the ifmail mailer in sendmail. This way memebers of the group news can
execute ifmail/ifnews (needed as send-ifmail is run by user news) and for
mail routing it is not possible to bypass the sendmail daemon.
That is not possible to bypass the routing.
