[Dovecot] Error while set mailQuota=0 with mbox and LDAP backend

Fri May 23 23:39:25 EEST 2008

Hi, all.

I have OpenLDAP(+qmail.schema), Dovecot, Postfix installed on RHEL 5.1
(x86_64), and they works fine with mbox format.

The problem is if i set 'mailQuota=0' in LDAP, postfix can't send mail
to recipient user. But it works fine with 'mailQuota != 0', such as
'10240'(10M).

What's wrong with my mail server setting? How can i solved this issue?

Thanks very much.

Bellow is the mail log from /var/log/maillog:
