Hi,

Thank You for example but I still don't know what I doing wrong.

I set that in master.cf

service doveadm {
     unix_listener doveadm-server {
     mode = 0666
     }
}
doveadm_password=foobar

My script now look like that:

$DOVEADM_PASS = base64_encode('foobar');
$sock = stream_socket_client('unix:///var/run/dovecot/doveadm-server', 
$errno, $errstr);
echo fread($sock, 4096)."\n";
fwrite($sock, "VERSION\tdoveadm-server\t1\t0\n");
fwrite($sock, "PLAIN\t$DOVEADM_PASS\n");
fflush($sock);
echo fread($sock, 4096)."\n";
fwrite($sock, "\tpiotr.rotter at active24.pl\tquota get\n");
fflush($sock);
echo fread($sock, 4096)."\n";
fclose($sock);

I get two times "-" and that in logs

dovecot: doveadm: Error: doveadm client didn't authenticate as 'doveadm'

Please give me any tip.
