There's not really a point here. You tend to want to target your
security to the domains with which you do business.

Out of the roughly 1,000,000 domains that sent us email (most of them
are forged, of course), and to which we sent mail (probably more than
5,000) over the last two months, how would you have the IT folks
decide which of them should use TLS?

In the absence of a specific request from a domain to use /only/ TLS
to communicate with them, I'd prefer to let the MTAs figure out if TLS
is appropriate. I really don't like working with the tiny work area
provided to manage address spaces, especially when there are
potentially so many to deal with (and where the rate of change is
probably several addresses spaces a week, adding and removing).
