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.
