Here is my example on perl

        socket(TSOCK, PF_UNIX, SOCK_STREAM,0);
        connect(TSOCK, sockaddr_un("$conf{quota_socket}"));

        if ($? != 0) {
                  #error here
        }

        #After connect on socket, dovecot returns "+" or "-". Just a simple
check for data.
        if (defined(my $answer = <TSOCK>)) {

                print TSOCK "VERSION\tdoveadm-server\t1\t0\n";
                print TSOCK "PLAIN\t$conf{'doveadm_password'}\n";
                TSOCK->flush;
                #'+' here
                $answer=<TSOCK>;
                print TSOCK "\t$local_part\@$domain\tquota get\n";
                TSOCK->flush;

                my $quota_data = <TSOCK>;


                #"+" if everything is OK
                $answer = <TSOCK>;

                close TSOCK;
}

Don't forget to set doveadm_password= in dovecot config(clearttext) and you
must encode password in base64 for using in a script (after PLAIN command).

PS
dovecot version 2.1.15 here.
