[Exim] permission denied?

I'm trying to get exim to the point where normal users can check the mail Q by using the mailq symlink to exim, but whenever a non-root user runs mailq, it just says: exim permission denied

What am I doing wrong? It's obviously running the program because there's no bash: infront of the exim, so it's obviously exim returning the error, but why? The /var/spool/exim directory is world readable/executable (only root can write), the files in that directory are world readable, whats wrong?

Thanks!
