Someone said that in an RBL would cause general mail
delivery problems, but I believe that might only apply to an
RBL applied to message headers in an MTA, which SURBLs aren't.

OPM uses the .1 bit, but it does it in the larger context of
127.1.0.x not 127.0.0.X, where .1 could perhaps run into the
loopback address.


I suppose we could start with the 2,4,8 bits and expand back
down to .1 if we feel it's safe later.  Does that sound ok?

Yes, individual entries would get the shortest TTL if it
appears on multiple lists.
