mailman

Sorry for a lot of messages, but I can't find the answer.

I'm using mailman.

The main list (mailman) works great, but when I create a test list, I 
have permissions problems.

The errors:
2008-07-04 11:36:18.585938500 delivery 11: deferral: 
Group_mismatch_error.__Mailman_expected_the_mail/wrapper_script_to_be_executed_as_
group_"qnofiles",_but/the_system's_mail_server_executed_the_mail_script_as/group_
"vmail".__Try_tweaking_the_mail_server_to_run_the/script_as_group_"qnofiles",_
or_re-run_configure,_/providing_the_command_line_option_`--with-mail-gid=vmail'./


Compiling:
#make --prefix=/var/mailman --with-mail-gid=qnofiles --with-cgi-gid=www
and
#make --prefix=/var/mailman --with-mail-gid=vmail --with-cgi-gid=www

The error is the same.

Thanks for any help.
Luiz.
