Not necessarily 'misleading'. Just not on the same time-base for
averaging, and not related to total bytes flowing.

Those exim children are probably only getting a byte or three every now
and then. Symptom resembles zombots hanging on the teat.

Check for how many unique IP there are.

I limit max_per to TWO, and drop really early on rDNS fail, so never see
anything even remotely close to what you've described.

Or any significant spam.
