Btw, the same applies to amavisd-new: in a typical Postfix setup the mail is queued by MTA before and after a content filter, with a controlled pipe width to amavisd-new, so such a setup is never subject to problems caused by bursty load or high peaks / mail storms, it just hovers at its admin-controlled (tunable) setting for the number of parallel streams to achieve consistent optimum overall mail throughput.
