Modern mail daemons let you explicitly configure this (ie. the daemon
itself does a setgid() before executing the pipe), rather than rely on
setgid-ness of the delivery programs. Certainly exim works like that,
and it is the sensible way.
The delivery programs that hardcode a group name, or even _the fact
that they change group id_, are broken.
