This is somewhat of a stability issue as I'm seeing a lot of remote mailservers affected.
The blackholes.us series of RBLs (geotargetted IP space by country) is no more, hasn't been for awhile. It has now been wildcarded and answers positive to all queries.

Sorry if this is known, I checked the archives and didn't see anything.

The blackholes.us series of RBLs (geotargetted IP space by country)
is no more, hasn't been for awhile. It has now been wildcarded and
answers positive to all queries.
The problem is that the domain has been abandoned, the IP block
where its nameservers live was returned to ARIN and reallocated, and
the new owner would like to get rid of the traffic.
We've told him that wildcarding will not make the traffic go away, and
I expect that in the next few days the domain will be turned off or
at least the name servers pointed at someplace harmless.
R's,
