What is your basis for this?
There are far more non-ISP servers (sending and receiving servers)
than there are ISP servers. ISP's carry the most volume and have the
most users, but in a head count of machines intentionally and
actively running MTA's, they hold a minority. Except for ISP's, where
the scaling makes it natural to end up with fewer sending machines
than receiving machines, there isn't a big difference in those
numbers, and at the low end of the scale the machines are often
identical.
