postfix virtual mysql + mailman

[sasuki]

hallo,

ich habe hier postfix so konfiguriert dass es mit den mysql virtual_maps und virtual_domains von syscp benutzt. Jetzt will ich auch mailman installierten es scheint aber gar nicht zu funktionieren, hier meine main.cf

command_directory = /usr/sbin
daemon_directory = /usr/lib/postfix
program_directory = /usr/lib/postfix

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
setgid_group = postdrop
biff = no
# appending .domain is the MUA's job.
myhostname = domain.tld
#mydomain = domain.tld
mydestination = localhost.localdomain localhost
mynetworks = 127.0.0.0/8
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
owner_request_special = no
unknown_local_recipient_reject_code = 550
virtual_mailbox_base = /data/syscp/main/
virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual_mailbox_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual_mailbox_domains.cf
virtual_alias_domains =
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual_alias_maps.cf, hash:/var/lib/mailman/data/virtual-mailman
virtual_uid_maps = 5000
virtual_gid_maps = 5000
virtual_transport = maildrop
alias_maps = hash:/var/lib/mailman/data/aliases
alias_database = hash:/var/lib/mailman/data/aliases
maildrop_destination_recipient_limit = 1

internet-liste-subscribe:   "|/var/lib/mailman/mail/mailman subscribe internet-liste"
internet-liste-unsubscribe: "|/var/lib/mailman/mail/mailman unsubscribe internet-liste"

wenn ich jetzt eine email an internet-liste@domain.tld schicke, bekomme ich folgende Fehlermeldung:

<internet-liste@domain.tld>: user unknown. Command output: Invalid user specified.

was hat das zu bedeuten, was mach ich falsch

Ich benutze Debian Sarge
