That is odd that blackholes.mail-abuse.org does not return a DNS listing.
There is a utility that you can use to check an IP address against rbl.
Obtain the source code, and there will be a file called site.h that has a
list of valid rbl DNS's.
As to why blackholes.mail-abuse.org is inaccessible.... I would email
their support an see if they're having a problem or what not.
