I think you understand what the error is telling you. You have to
either make sendmail run the pipe as group mailman or you have to make
the wrapper expect to be run as group mailnull.

I have no idea how the FreeBSD port sets the expected group for the
wrapper. This is a FreeBSD Mailman question. In our Mailman
distribution, the expected group is compiled into the wrapper from the
--with-mail-gid option to configure.

The things you quote above seem to say it should be doing the right
thing, but I have no way to know.

What does the rest of the makefile do with MAIL_GID? Can you determine
if it is put in a file somewhere and what that file actually contains?
Perhaps you can fix it by changing that file if that's what it does.
