Postfix/mailman problem

I wrote about trying to get Postfix working with Mailman:

I found that if I turned off enforcing the chcon would succeed.

However, when I turn enforcing back on, Postfix is still unable
to invoke the postfix-to-mailman script.  With enforcing off, it
works fine, so I'm really curious as to what I need to do to make
it work properly with enforcing on.

Thanks,
