[Mailman-Users] Group Mismatch Error

Time for this old chestnut again, but with a bit of a twist.

Postfix (latest stable), FreeBSD 6.2, latest version of Mailman.

Attempted to send a test message to my list.

ommand died with status 2: "/usr/local/mailman/mail/mailman post
    netoplist". Command output: Group mismatch error.  Mailman expected the
    mail wrapper script to be executed as group "nobody", but the system's mail
    server executed the mail script as group "mailman".  Try tweaking the mail
    server to run the script as group "nobody", or re-run configure,  providing
    the command line option `--with-mail-gid=mailman'.

Is there something blindingly obvious that I'm missing?
