Hi, I'm trying to evaluate the block lists that are available to be used at SMTP connection time with reject_maps_rbl, and wondered if someone had any input. I have spent quite a bit of time researching many of the block lists, but much of the information is somewhat old and I'm concerned that it's outdated and unreliable.
Is there a "best practices" document that includes recommendations or suggestions on which RBLs to use for which purpose? I'd also like to be able to gather some stats on them, such as how many rejects, queries, perhaps even the IPs that were rejected, so that I may collect this information and create some historical data. I'm currently considering multi.uribl.com and multi.surbl.org as the top two, but even with that I've read that in the past there were great concerns that they'd get knocked offline and what the implications would be for the postfix server. Does anyone know anything about these stats? http://www.intra2net.com/en/support/antispam/index.php_sort=accuracy_order=desc.html There certainly isn't a shortage of block lists to choose from: http://www.dnsbl.info/dnsbl-list.php The spamlinks site has done a great job of indexing the RBLs, but it doesn't say anything about what kind of reputation they have, or if they're really suitable for real-world use: http://spamlinks.net/filter-dnsbl-lists.htm Ideas greatly appreciated. Thanks, Alex
