Do what it says. If you installed from source, rerun configure, adding
or changing the option --with-mail-gid=mailnull, and then run 'make

If you installed from a package, there may be some package dependent
way of changing the group the wrapper expects.

Or, if you can, you can tell sendmail to run as gropp 'mailman' when
executing the wrapper.
