Since you like to quote from the
sendmail results, perhaps we should look again at their conclusion:

Perhaps you might look at their data and note that the conclusion is
not
justified for short messages like spam.  The data speaks for itself.

You're certainly free to reach any conclusion you care to.  The people
who ran the numbers you are quoting reached the conclusion that it was
well with acceptable ranges.  Our own numbers here lead us to the same
conclusion.  The largest inbound receivers in the world have come to
that conclusion.  If you want to hold out a minority opinion, that's
certainly your prerogative.

Microsoft and Yahoo have resources that the average site does not.  Not
everybody can afford IronPort boxes or specialized MTA software like yours.
Endorsements from those sites does not make it a good idea, and disagreeing
with them does not make it a minority opinion.

Crypto accelerators would obviously solve the problem.  As a hardware
engineer who works with DSP's, I would personally benefit from an expanded
market for such accelerators.  Designing them is both enjoyable and
profitable for me.  However, as an Internet citizen, I would not like to see
that become part of the price of admission for email.

By using a DSP core in an ASIC with the right communications interface, such
an accelerator could be a $10 adder to a motherboard, if that, but I don't
see things going that way.  If they do, I'd change my tune quickly.  I
suppose something could be built as an external USB 2.0 device for
relatively low cost.  Go ahead.  Popularize this protocol and put me in the
hardware accelerator business.
