I do not belive it, and I have pointed out the most obvious reason why.
There are always tradeoffs between performance and resources.  The more
you keep in memory the less you need to keep on disk, but more memory is
required to do it.  The more parallel network connections you make the
faster delivery will be, up to the limit of the network's speed, but you
need more running processes to do it.  Both require more memory than the
old stand-by sendmail, which means you will run out of physical memory
sooner (optimized code seems always to be larger).  When that happens
you will start swapping, and when that happens you kill the benefits of
these "improvements".

PB> I can't talk about the details because it's under non-disclosure.

Oh, goodie.  Not only does it sound too good to be true, it probably is.
Seriously, if this MTA is so good, why are the developers hiding?  The
answer: because it is not as good as they claim, and they know it.  Call
me cynical, but claims of "proprietary technologies" are largely a
smokescreen.

sendmail does no such thing.  This is why programs like bulk_mailer
exist.  Check your outgoing alises, or a wrapper around sendmail.
