Status of DEAD

Uh-oh! On or about September 19th, the domain seems to have expired. Now when you visit the website, you are informed that the domain is for sale. Also, you'll now find a wildcard A record in DNS, meaning that any lookup of any host name in DNS under will result in a positive response being returned.

The net result here is that due to the domain now having a wildcard A record, any users of the Burnt Tech DNSBL now find that they are blocking all inbound mail. If you were using the blocking list to filter inbound spam, you'll need to remove it from your mail server or spam filter configuration immediately, as it is going to impede your ability to receive any mail.

Reviewing Internet Archive versions of the Burnt Tech DNSBL website, it appears that the list has been in action since at least 2006. From a 2015 archived copy of the website: "The Block List runs entirely automated and designed to avoid listings of spamtrap hits due to bounces of forged spam, virus bounces, and "real" mail servers emitting the occasional spam. It tries very hard to avoid listing legitimate mail sources. It does not attempt to list every possible spam source."

No other information was available regarding ownership, listing criteria or history of this DNSBL.
