Hello Ibrahim,

The load that you observe, where does it come from.. raw processor 
chewing or I/O?

Have you seen qmail-smtpd processes consuming huge ammounts of CPU?

Are you using an alternate qmail-queue? Is that alternate qmail-queue 
process responsible for eating all your CPU?

Are you sure all the RBLs you're consulting are replying in time?

Mind if i ask how many user accounts and an estimate on the amount of 
accepted messages per day?

Regards,

Hugo Monteiro.
