|I think it's a good idea to share such tables. (If the blacklist |maintainer agree to share his entire knowledge) |Regarding updates the file sizes should be much lower if they contain |only the changed values.
The trick is - spammers currently can't get their hands on any entire database - so that gives a margin of protection to the DNSBL. However, if that same DB could be distributed in a way that would still require a brute force attack to extract all of it's secrets - but still provide nearly instant queries... then that would be something wouldn't it. hmmmmm (wink - <something up sleve> <wheels turning>). _M |My opinion about sharing tecnologies: |It's a little bit programming work but why not use P2P tecnologies to |search for special signed file names containing the update for |a certain |day? If this file is signed with a digital certificate it |should be save |to run such a update over P2P in automatic mode. The maintainer of this |list can work from everywhere arround the world. He must only put the |daily updates in the P2P network. | |Spammers shouldn't have any advantage from such public blacklists |because they are already able to check DNS based blacklists if the IP |they use currently to send out spam is blacklisted somewhere. They are currently restricted by bandwidth and throttling mechanisms. However that can still be countered by distributing parts of the rulebases among different nodes and making queries from random peers for data not stored locally on a given client. |Maybe daily updates are to slow for effective spam filtering and also |hourly updates would ask some changes on the local anti spam filters |(for example a queue-wait for suspiciuos messages) Gutsy comment. I suggested a queue-wait for suspicious messages and got into big trouble about the viability of introducing any delay - ever. I suggest you run for your fire-proof suit unless opinions have changed without notice. _M --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
