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:
