  Agreed.

  MTA's need to record, and publish such information.  When taken
together, that information tells you which MTA's are probably OK, and
which aren't.

  Getting rid of DUL & Blacklists would be useful.  There are many,

  The main problem is that it's easy to maintain a DUL or blacklist,
and much more difficult to maintain a whitelist.
