I believe that this statement is due to misbelief and ignorance rather than real testing.

Note that I don't have load testing experience with postfix yet, so that may be a problem. If so, I'll return to sendmail because I was previously doing this with a single-core 1.4ghz athlon processor and 2gb of RAM. So yeah, not much horsepower required. Recent system is 16gb 8 core, so if postfix can't keep up then it's the problem.
