	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.

	Indeed.  Hence my references to the two main papers published so 
far on this topic, one by Rob Kolstand and one by Strata Chalup.

        These are some of the standard techniques, yes.
