Agreed, but no one has ever been able to pinpoint why.

I'm running:                  

But again, please note that my throughput and server load have NEVER been
due to MS/SA. Whenever I had a large backlog in the incoming queue, if I
shut down all the MTA processes, then MS/SA would scream through the queue
just fine. The load has always been due to the resources taken by the MTAs.

In any case, my point was simply that out of the available MTAs, I have seen
a drastic performance improvement when using zmailer vs sendmail and exim.
