1) test an individual domain name against online blacklists? Do this with a script that uses dig to query all the blacklists. Obviously this isn't for more than relatively casual use. 2) test all the domains in a file against online blacklists? Do this with a wrapper script that calls script (1) against each domain in your file. However, if this is used often you may exceed usage limits on some blacklists. 3) test all the domains in a file against downloaded blacklist files you've retrieved from the blacklist hosts? Use a script that downloads blacklists with 'curl' or a scripted ftp client. Use 'awk' to convert the files into a common format containing just the domain names, combine them and eliminate duplicates with 'sort', and do a mass comparison with 'column' to produce a sorted list of matches and/or non-matches. This is a bit more work to write, but should run fast and can't break a blacklist's online usage limits. 4) what do you want to do if a comparison matches/doesn't match a blacklist? Martin
