DOB's home is here: http://support-intelligence.com/dob/
It clearly says it's a BETA service. It's not blocking queries from us, 
currently, but it has in the past been a bit unreliable, due to it's own 
growing pains. It's a free service, so there's no requirement of 
transparency or accessibility. Use it or don't. I've found it quite 
useful simply because nobody else has made this data available, so it's 
a good thing for use in SA META rules.

Arguably, part of the reason that DOB was needed is because URIBL & 
SURBL weren't catching everything and/or were not listing new spammer's 
domains fast enough and, certainly, DOB picks up some of that slack. 
However, there is now a third major URI blacklist in the same league as 
URIBL & SURBL that is more FP-save than DOB... and, in fact, at least as 
FP-save as SURBL, and this newer URI blacklist catches many of the spam 
domains missed by SURBL & URIBL.

This newer URI dnsbl is called "ivmURI", short for "invaluement URI 
blacklist"

ivmURI isn't meant to replace SURBL & URIBL. But it complements them 
well. All three lists, ivmURI,  SURBL, & URIBL will all catch spammer 
domains not found on the other two URI blacklists, which is why I use 
all three in my own spam filtering. Frankly, there is not even a close 
forth URI blacklist in terms of effectiveness and in terms of low FPs.

I believe that those who originally found a need to use DOB will find 
that ivmURI does a better job of picking up the domains missed by both 
SURBL & URIBL, while being more FP-safe and more reliable than DOB.

FOR EXAMPLE, SEE:

Unlike all of these other dnsbls I've mentioned, ivmURI does requires a 
subscription for access. Contact me off-list for more details and for a
