I am trying to setup dovecot from this tutorial: http://library.linode.com/email/post...tu-10.04-lucid

When I use Webmin to start dovecot I keep getting this error.

Failed to start Dovecot :
doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 19: Unknown setting: global_script_path


Here is my config file


Code:
protocols = imap pop3
log_timestamp = "%Y-%m-%d %H:%M:%S "
mail_location = maildir:/home/vmail/%d/%n/Maildir

ssl_cert = /etc/ssl/certs/dovecot.pem
ssl_key = /etc/ssl/private/dovecot.pem

namespace type=private {
    separator = .
    prefix = INBOX.
    inbox = yes
}

protocol lda {
    log_path = /home/vmail/dovecot-deliver.log
    auth_socket_path = /var/run/dovecot/auth-master
    postmaster_address = postmaster@example.com
    mail_plugins = sieve
    global_script_path = /home/vmail/globalsieverc
}

protocol pop3 {
    pop3_uidl_format = %08Xu%08Xv
}

auth default {
    user = root

    passdb sql {
        args = /etc/dovecot/dovecot-sql.conf
    }

    userdb static {
        args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
    }

    socket listen {
        master {
            path = /var/run/dovecot/auth-master
            mode = 0600
            user = vmail
        }

        client {
            path = /var/spool/postfix/private/auth
            mode = 0660
            user = postfix
            group = postfix
        }
    }
}


How would I fix this? I did some research and apparently this file wont work with a 1.2X dovecot version. I am new to dovecot and not sure what to do. has that command been replaced with another? or do I need a diff config all together? Any help would be gladly appreciated. I'm running on Ubuntu 11.10 Server edition.
