As noted, #2 is solved already.  Also, /128 will no longer print (commit
945353a2).  

But your #1 makes little sense to me:  discovery.razor.cloudmark.com/22.  How
do you know that EVERY IP returned from a DNS lookup is always going to be a
/22 mask?  What if they get assigned a new /24 net tomorrow, and add an IP from
that /24 to the DNS RR?  Then your rule addition is no longer valid.  What you
are attempting to do ultimately sounds like a bad idea, and not one that we
should hack around to support.
