When trying to send an email to test-request@halemail.dyndns.org, I get this error message... Can someone tell me what to look for to fix it?

The Postfix program

<test-request@halemail.dyndns.org>: Command died with status 2: "/var/mailman/mail/wrapper mailcmd test". Command output: Failure to exec script. WANTED gid 12, GOT gid 99. (Reconfigure to take 99?)

Thanks!
