Well yes, it could be done with certificates, but it can also be done
via some type of "root server" system like DNS uses.  A database
distributed among many root servers from the registrars is proven.
Tracking valid servers seems much easier to track rather than
blacklisting IP's that are not mail servers at all or are abusive
servers.  IMHO I don't think it would be that horrible of an idea with
the right amount of notification and education to state something such
as "register your mail servers by this date or risk service
interruption".  Of course this period would be several months, if not a
year+ .

Politics and legalities are 95% of the reason a lot of good ideas have
yet to materialize.
