Yup, virus-filtering only. :-) Although we *are* running spamd on the same
machines - our inbound mail servers access spamd separately for legacy
reasons. We plan on using amavisd's built-in SpamAssassin filtering soon.
I was still seeing plenty of available CPU during heavy lock contention,
even with spamd grabbing as much CPU as it wanted.

Yes, we've discovered that. We had to CYA a little and deliberately
over-provisioned the CPU and memory in these machines.
