The load is roughly a combination of resources programs are waiting for,
and that doesn't necessarily have to be CPU cycles, but something else
could be your bottleneck, like disk IO.

I suggest finding the real problem. You could throttle sendmail (or any
MTA) a bit by lowering the point where it starts temp-failing email
(with an 450), but that's just a workaround.
