   In the next few months, I will implement at database listing domains for
which one or more MX'es have this problem and Postfix will be configured to
reject mail from those domains. Essentially it will be an RBL-style
database, automatic retesting etc., although until someone implements a
DNS-based database engine for Postfix, I'll have to use something else
(probably the mysql one, suggestions welcome, preferably something that
works across a network).

   I would not mind at all if it became more widespread than just a
K-net.dk thing.

   Stuff like missing postmaster, permanently down hosts and possibly known
invalid sender addresses are also one the list.
