Any list which you trust enough to make the decision *which* mails you
accept for you.

Which would leave "none" for me.

Even sbl.spamhaus.org contains a blacklist, which sometimes lists
because of the name the machine has (CBL that is).

DNSBL has information on many RBLs together with statistics on their
effectiveness:


http://stats.dnsbl.com/

Other popular RBLs besides Spamhaus include Spamcop, PSBL and uceprotect.

As Ralph says, any RBL should be used with a certain amount of caution
as it has the potential to cause FPs (some more so than others). An
alternative approach is to use such RBLs as part of a scoring system
such as SpamAssassin. This is particularly useful for RBLs that you
don't trust to outright reject mail at the smtp level.


If you want to improve on the performance of sbl-xbl.spamhaus.org, I
would first look at switching to the combined zen.spamhaus.org zone
which also contains the pbl.spamhaus.org zone. My own data shows
sbl-xbl.spamhaus.org to block around 50% of spam whereas
zen.spamhaus.org hits on around 90% of spam with very few FPs for me -
YMMV. You should monitor performance closely.

Anyone have any experience dealing with SURBL?* I have a client who's domain and IP is not listed in SURBL, but their client in China is using SURBL and my client's emails are getting blocked.* Can't seem to find how SURBL is blocking them

Could the client in China either have an old copy of the feed, or maybe a
Chinese ISP keeps an older copy cached of the feed?

The Chinese client could also whitelist your client.

I've moved their website to 3 totally different ISPs.* LayeredTech, Superbhost, and now Savvis colo.

Not sure on the whitelist, we've having a hard time getting anyone in the China office that knows how this is setup.* I guess the previous tech that set it up left.

Depending upon your outcome, there are other methods you can use to
modify for better results. You may find inserting the RBL in sendmail
as a successful choice.


In case you do not, What I use is a combination of scoring within
SpamAssassin on the public RBLs and maintaining my own RBL on my
local mail servers (See http://www.corpit.ru/mjt/rbldnsd.html).


I got too many false positives off publicly available RBLs, but
adding up the number of RBLs a sender 'hits' made my SpamAssassin
scoring method VERY ACCURATE!


Good luck and keep fighting!

The Chinese government also blocks a lot of stuff. Maybe you can get them to
pony up for a roadtrip? ;-P

That doesn't mean that you can't give it a meaningful subject. Thanks.
