Mail quota warnings

Hi,

We have kind of same problem like that thread:
http://www.howtoforge.com/forums/showthread.php?t=65760

We have multiserver setup, adminpanel, mailserver, webservers and nameservers.

Problem is that masterserver don't send quota warnings to clients, it sends to the admin email.
Masterserver mail configuration part in the master database.

Code:

[mail]
module=postfix_mysql
maildir_path=/var/vmail/[domain]/[localpart]
homedir_path=/var/vmail
pop3_imap_daemon=courier
mail_filter_syntax=maildrop
mailuser_uid=5000
mailuser_gid=5000
mailuser_name=vmail
mailuser_group=vmail
relayhost=
relayhost_user=
relayhost_password=
mailbox_size_limit=0
message_size_limit=0
mailbox_quota_stats=y
realtime_blackhole_list=
overquota_notify_admin=y
overquota_notify_client=y
overquota_notify_freq=7
overquota_notify_onok=n

Mail log shows only that it sent mail to the admin mail. No other errors.
Admin mail is in the same server as the client mailboxes.

Code:

Dec 10 00:30:01 postfix/qmgr[29925]: 754F3A006D: from=<root@masterserver>, size=676, nrcpt=1 (queue active)
Dec 10 00:30:01 postfix/smtp[10890]: 5EF7CA0065: to=<adminmailaddress>, relay=mailserver:25, delay=0.21, delays=0.02/0.01/0.16/0.01, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as E77278A048)
Dec 10 00:30:01 postfix/qmgr[29925]: 5EF7CA0065: removed

Can i somehow debug what goes wrong or what happens? It started when we moved masterserver from Opensuse to Debian. All the others things work fine.
We don't use webserver quota warnings, so i don't know if that works.

Regards.

 

Anyone can help?
