how to disable them?
I have setted "Daily E-Mail limit per DirectAdmin User" to 50,but I still got messages which said that the user had sended too many emails beyond the limit number.
 
It could be a couple of reasons. If the user is a spammer, why not suspend the account?
If you don't want to do that, you should investigate why he is sending out so much mail, is there a trojan or a spambot or is his account hacked and external party's are abusing his mail account?
 
Do you have the latest exim.conf and exim.pl that block sending emails from user account over the limit?
 
I have some customer that sent many email per day over 200 too.
But it's not affect with server much.
