$prefix/mail/mailman

It is a compiled binary wrapper (source is src/mail-wrapper.c in the
distribution) that ultimately calls one of the Python scripts in the
scripts/ directory (e.g. scripts/post) to handle a message to Mailman.
It is a compiled binary because it needs to be SETGID and SETGID isn't
honored on script files.

It's sole purpose is to be SETGID and set the effective group for the
process to Mailman's group, and to check that it is invoked from the
expected invoking group to prevent just anyone from running it. See
the FAQ at <http://wiki.list.org/x/tYA9> for more on this.
