Here's the widget I use, on the rare occasions I check a domain against
DNSBLs by hand:

====
#!/bin/bash

host $1.multi.surbl.org
host $1.multi.uribl.com
host $1.dbl.dnsbl.
host $1.viauri.dnsbl.
====

We have a datafeed subscription for Spamhaus (the dbl line would be
dbl.spamhaus.org on public DNS) and viauri is our own local URI blacklist.

IP blacklists are tricker because you can't just use the IP as-is but I
haven't felt the need to check those by hand often enough to script it.

FWIW, I wouldn't remove a local DNSBL entry unless it's proven to be
nonspam;  it saves the hassle of relisting in response to a customer
report including the domain later, that would have been blocked had that
entry remained on your local blacklist...
