How do I trace what user is causing mysql to skyrocket the server load? I'm using cpanel (stable), phpsuexec, mysql 5, centos 4.4
I have converted all accounts to :fail:
What else could I do to optimize exim itself? Also, how do I apply RBL to exim? I know there are some info in cpanel, but I'd like various advices from people. I found some that did not even work anyway. Thank you.
My configuration is below:

I'm using MySQL 5 also. I have box trapper disabled, spam assassin enabled, mailman enabled.
is this recommended?

exim stats is the one that appears most in mytop too...it seems to be the cause of the server load spikes.
