MAILDROP v postfixu

Ahoj,

vim, ze se resi porad nejaky maildrop,... mam nainstalovan maildrop a s tim take maildrop-mysql. Uzivatele v postfixu mam resene pres mysql tedy virtualni, kdyz zadam v console: maildrop-mysql -d info@domena.cz zobrazi se cerny radek, ale kdyz zadam nezanmou adresu kterou v mysql nemam, napise se mi invalid user, mam to chapat, ze tedy je maildrop-mysql funkcni? Proc tedy mi pise v logu tuto chybu:

Nov 14 08:44:07 www3 postfix/pipe[26395]: 16E601B1B1C: to=< info@domena.cz >, relay=maildrop, delay=0.06, delays=0.03/0/0/0.03, dsn=5.1.1, status=bounced (user unknown. Command output: Invalid user specified. )

v master.cf mam toto (vycetl jsem to nekde na internetu, ze to funguje s virt. uzivatelem:

maildrop  unix  -       n       n       -       -       pipe
      flags=ODRhu user=vmail argv=/usr/bin/maildrop-mysql -d ${user}@${nexthop} ${extension} ${recipient} ${user} ${nexthop}

v main.cf mam toto:

...
#mailbox_command = /usr/bin/maildrop-mysql
maildrop_destination_recipient_limit=1
virtual_transport = maildrop
#virtual_transport = virtual
virtual_minimum_uid = 77
virtual_uid_maps = static:77
virtual_mailbox_base = /home/vmail
...

Muzete mi prosim nekdo poradit na co se soustredit? Googloval jsem a nikde nic nenasel :-(
