As mentioned by Nigel earlier, mounting your oft-changed filesystems
with the noatime option is a good bet:
mount -o remount,defaults,noatime /var
...or /var/spool, or /var/spool/mail, or whatever the mount point(s)
your Qmail spools/queues and your courier mailboxes live under.
When I first found that one out it was a real "Eureka!" moment. It
should, ideally, give you a bunch more performance from your "tired"
systems.
