Changing the context on /usr/lib/mailman/mail/mailman from lib_t to
bin_t does get things further, and on to the next set of denials.

The avc messages:

The postfix messages:

I'm not sure whether it's worth trying to chase every denial down this
path or if there is a better fix that can be applied.
