Quota Warning Problem.

[Anthony]

Hi   I was setup a qmail server with ldap patch. Everything work fine except some problem.   I set ldapdefaultquota (10000S, 100C) and quotawarning ( Quota Exceed !) in the ~/control directory. When I try to send a large mail to one user of this server, the mail will drop and returned to the sender because the mail exceed the quota setting. But no warning messages send to the receipent. Why ?   It seems the quota function is worked except quota warning.   I used qmail-showctl to check the system, it could be show quotawarning messages in the list.   So Is there any etting required ?   I spend a lot of time to solve this problem but still no solution.   Pls help !   Thanks
