Even after the issue causing this particular problem is fixed, as a general
protection against SpamAssassin accidentally sending data that the DBL thinks
is an IP address (correctly or otherwise), URIBL_DBL should never fire if the
DBL returns 127.0.1.255.

Since the DBL is fundamentally represented as a dnset via rbldnsd, the DBL's
view of what is and is not an IP address is not perfect.

For example, the DBL thinks that "example.com.1" is an IP address.

$ host example.com.1.dbl.spamhaus.org
example.com.1.dbl.spamhaus.org has address 127.0.1.255

For our local Exim MTA-level/DBL integration that we're using in production at
Berkeley, we make sure we have a sane looking TLD before sending a query off to
the DBL, and additionally, we ignore any 127.0.1.255 return codes.
