Hi I'm new and I like SURBL
by Paul Schwarz 01 Dec '04

01 Dec '04

what are others thoughts of the effectiveness of SURBL , risks of false positives, CPU usage, etc I'm currently doing my spam checking in this order sbl-xbl.spamhaus.org - reject at SMTP level standard greylisting SURBL - using multi.surbl.org How are you guys doing it and do you have any suggestions ? Low false positives are my goal in my setup. I wondered if surbl should replace greylisting or RBL or should just complement. thank you Paul

Paul, if you are still interested in greylisting you might consider a solution that allows you to run SpamAssassin at SMTP time. I use sa-exim (I believe there are others for different MTAs) and this allows me to greylist based on score. For example, if the score is above 3 points then it is greylisted, otherwise it is immediately let through. However, I would go with Chris's suggestion first and see if you even need to bother. In our situation, we have to be very liberal on the score to keep the FP's down, so we use greylisting on the uncertainties.

With SURBL I don't think you need it. But if you have the time and don't mind waiting sometimes 20 minutes for some companies to resend, then go ahead. I think you will be very happy with SURBL.

Who > maintains it etc. Individual lists (data sources) may have their own internal whitelists which cause exclusions from those lists, but there are also shared whitelists which get sorted together and globally applied across all SURBLs. The former would be largely invisible to the outside world. The latter can be found at: http://spamcheck.freeapp.net/whitelist-domains.sort but it includes a lot of high-level geographic domains. Raymond, Various people are using our whitelist. Perhaps we could consider putting it on the rsync server for more efficient transfers.

RE: hotnudiegirls.com URI as false positive

1) Dude that is one hell of a cool domain name for a non pron site! Cool!! 2) quasirhombicosidodecahedron.com also rocks as a domain name! 3) Your original complaint, doesn't exhist :) You are NOT listed. Something is up. We have seen these more then a few times. hotnudiegirls.com is not listed in ANY SURBL. www.rulesemporium.com/cgi-bin/uribl.cgi to check it out. I have no idea if it is corrupt cache data, or some sort of goofyness in the SA code. Is it possible we have a FUBAR SURBL mirror? I've cc'd just about anyone having any clue to help.

Who's job is it? That line scares me. You want to solve the spam problem? You can't do that with a narrow net. You must fight war on all fronts. You educate the legit users on what not to do. This has been all over the news recently. Everyone thinks everyone else is a spammer, but not them. I'm also VERY surprised at your comment. More then a few time YOU have educated people who have contacted us for removal from SURBL. >We want to list as many true spammer domains >as we can find and also prevent legitimate domains from being >listed. Again, legit? Once ANY company hits a spamtrap, IMHO, they are no longer legit. Not until they find out how they hit that trap. Possibly they purchased, as in gave money to a spammer, a list. With education, they will NOT do that again. Thus reducing income for spammers. Possibly they have an xploitable web subscription form? How the hell would they know unless someone tells them? *snip* > >The goal with a greylist should be to cast a wider net but >to eventually filter those down to some truly black entries >that can be listed more broadly on full blacklists. > My goal is to stop spam. Using any method. Education is probably THE biggest way to do this. Imagine if all the clueles users suddenly could spot 100% of spam emails, and NOT fall for them. Problem solved. Its the whole teach a man to fish thing. And I'm not rehashing the argument about SURBL. I clearly state I DO NO list what I want to list. I list what makes Jeff happy :) --Chris
