Dear all,


When i try to send mail for 2Mb into a local user mailbox with only 1Mb left, it recorded in log file => "2004-05-24 08:00:00 xxxx-xxxx-xx == xx@??? R=mysql_user T=mysql_delivery defer (-22): mailbox is full (MTA-imposed quota exceeded while writing to tmp/1084737..... bla bla bla" , and the xxxx-xxxx-xx-D and xxxx-xxxx-xx-H is still in the /var/spool/exim/input/ folder.

but it dind't return any bounceback email to sender, i wonder where can i configure to make it works.


Thanks !
