>Description:
When installing mailman with the POSTFIX option set, MAIL_GID is set to mailman.  This results in the following error when trying to deliver to mailing lists:

Group mismatch error.  Mailman expected the mail wrapper script to be executed as group "mailman", but the system's mail server executed the mail script as group "nobody".

According to /usr/local/share/doc/mailman/FreeBSD-post-install-notes, MAIL_GID should be nobody.
>How-To-Repeat:
Install mailman with the POSTFIX option set (in the dialog screen).
>Fix:
Install postfix with "MAILMAN_GID=nobody" in the environment, or change MAIL_GID for postfix in the port.
