The SPAMROUTING test uses the IP address to attempt to determine the
location of the server; it doesn't check the reverse DNS (since a large
percentage of mail servers are missing a valid reverse DNS entry, and
there's no way to know the location for a generic TLD).

The problem here is that the SPAMROUTING test didn't have the 80/81 Class A
IP ranges listed. The next release will include them.
