[Mailman-Users] Failure to exec script. WANTED gid 0, GOT gid 12. (Reconfigure to take 12?)

[Support]

Hi,

I set up mailman 2.0.12 on RH7.3 running sendmail.(sendmail running as
root, apache as nobody,mailman running as mailman)

i created a list, allowed FollowSymLinks in pipermail alias in apache,
added the appropriate aliases in the /etc/aliases file, and added a
symlink /etc/smrsh/wrapper -> /home/mailman/mail/wrapper


When i try to subscribe a test user to the list I get a subscribe
notice, I reply, then I get an email with this error.

I looked this up in the mailman archive and they say that it's a postfix
problem where postfix executes the wrapper as the owner of the aliase
file(root)and the remedy is to change the owner to mailman but, 

1- im not running postfix
2- is changing the owner of /etc/aliases to mailman a good idea?

is there another way of solving this????

thanx,
