There should be messages in Mailman's error and qrunner logs about this,
but the qrunners should be running as user:group mailman:mailman so none
of the setgid stuff should affect that.

I don't think I can be of further help here. mailmanctl should be
ensuring that the qrunners are running as user:group mailman:mailman and
the setgid bits (if honored) should ensure that the CGIs and mail
delivery are all running as group mailman and the mailman group should
have permission to read (and where necessary, write) these files.

I do not know why this isn't working in your case. Perhaps you should
ask RedHat.

So it is part of the RedHat package.
