The NJABL blocklist has shut down for good. The zone files are empty and are expected to stay that way for a while.
Anyone using NJABL, either for yes/no delivery decisions or as part of a scoring system, should remove that blocklist from their setup.
The RFC-ignorant blocklist announced on 9/15 that it will be shutting down service. I commend Derek and his team for how they’re handling the shut down. All too many blocklists have been shut down due to owner burnout with disastrous consequences. Most of these lists did things like listing the whole world or just pulling domains out of the roots. Both types of shutdown methods cause...
The Five-Ten website has a notice that they have retired the blacklist. Five-Ten wasn’t the greatest list for blocking mail, they aggressively listed senders and there were a number of false positives against a standard mail stream. But it was useful as a touchpoint. If I had a client that wasn’t listed on Five-Ten that told me something about their normal practices.
I updated the Wiki a few weeks ago when I heard, but don’t think I posted anything here. Comcast has changed their delisting form page to . The old form is currently non-functional. You can fill it in, but it’s unconnected to anything on the back end and it won’t result in an IP being delisted from the various Comcast blocklists. My understanding is that the old form may come...

DNS Response Policy Zones allows companies running recursive resolvers to create a zone that will not resolve specific domains. This is a second layer of filtering, if a spammer manages to get an email with a malicious link into the inbox then the ISP can still protect the user from...
Recently, an abuse desk rep asked what to do when customers were complaining about being assigned an IP address located on a blocklist. Because not every blocklist actually affects mail delivery it’s helpful to identify if the listing is causing a problem before diving in and trying to resolve the issue. Find out whether mail is actually being blocked, or whether the customer just went to...
Two changes at the Comcast Postmaster page that I think are worthy of mentioning. They have set up a RSS feed for updates and changes. Visit and click on the RSS feed link in the right hand column. They have implemented changes in their unblocking script at . This form will only assist in unblocking if the error you received contains the error code BL000000. For all other blocks, please follow...
