cannot poll mails for users frm maildir

[Mitul Limbani]

Dear Users,

I have installed qmail on my server.
every thing is proper mails get accumulated in the Maildir for the
respective users directoy..
Now the only hitch is i cant retrieve mail from the users box...

I am using qmail-pop3d and to start it i m using this script..

start() {
    if check; then
        echo "$PROG is already running"
    else
        echo -n "Starting $PROG..."
        if [ -e $CDB ]; then
            supervise $DIR \
            tcpserver $VERBOSE -c$CONCURRENT -x $CDB -u$USERID -g$GROUPID 0
$PORT \
            qmail-popup $HOST $CHKPASS $COMMAND Maildir \
            2>&1 | setuser $LOGUSER accustamp \
            | setuser $LOGUSER cyclog $FILESIZE $FILENO $LOGDIR &
        else
            supervise $DIR \
            tcpserver $VERBOSE -c$CONCURRENT -u$USERID -g$GROUPID 0 $PORT \
            qmail-popup $HOST $CHKPASS $COMMAND Maildir \
            2>&1 | setuser $LOGUSER accustamp \
            | setuser $LOGUSER cyclog $FILESIZE $FILENO $LOGDIR &
        fi

        if [ "$USESUBSYS" = "y" ]; then
           touch /var/lock/subsys/$PROG
        fi

        echo "done"
    fi
}

but still m not able to poll for the mails...
