There are a few problems with the RBL list you're trying to use
1. You're querying the same data multiple times. sbl-xbl.spamhaus.org is
the same as sbl.spamhaus.org + xbl.spamhaus.org. Also, cbl.abuseat.org
is incorporated in the XBL. dnsbl.sorbs.net is an aggregate zone of most
of those that you've listed. See http://www.au.sorbs.net/using.shtml
2. mail-abuse.org is defunct
3. You can't query a righthandside blocklist (ie one that lists domain
names, not IP addresses), in this manner. rhsbl.sorbs.net is useless in
this context
