I've been specializing in e-mail system administration for about ten years, and doing large systems & performance tuning of e-mail systems for about six. I can tell you from personal experience that Postfix is better at handling them out-of-the-box than any other I know of.

                          The trick to speedy turnaround is in the MTA
 configuration.
Indeed. Hence my references to the two main papers published so far on this topic, one by Rob Kolstand and one by Strata Chalup.

                 This is chiefly achieved by using multiple queues, as well
 as severely reducing the timeouts such that email being sent to
 unreachable/overloaded mailhosts are quickly moved to the bottom of the
 delivery stack.
	These are some of the standard techniques, yes.
