Joe Jobbed by a scammer and AbuseButler
by Ron Guerin 06 Aug '08

06 Aug '08

I ironically now find tighturl.com listed in SURBL as the result effectively being joe-jobbed by some sleazeball promoting a work from home scam and using a tighturl link to a fake removal page, which was blocked by me within the 45th access (and is now probably around 10,000 hits which redirect to a page explaining the inadvisibility of clicking on links in spam or putting your email address into a spammer's removal box). AbuseButler has yet to respond to mail sent late Saturday night to abuse(a)abusebutler.com about the matter, and they clearly are not resolving URLs to their destination as I would have expected from a data source used by SURBL. Just what is the SURBL policy about listing URLs that have not been resolved to their destination, and about the quality of the data accepted into SURBL? I find the lack of a response from AbuseButler to its abuse address an indication that they're not running a responsible or reliable service over there. - Ron

Yes, we would not get rid of OB entirely ever. It does have some good data, but with too many FPs. The goal would be to keep as much of the good data as possible while eliminating most of the bad. Unfortunately some of the good data may be thrown out with the bad; baby with the bathwater, so to speak. IMO FPs are much worse than FNs, so some increase in FNs balances out a decrease in FPs. Trying to decide if it's worth doing.... Jeff C.

I think we probably can't reveal the exact listing criteria in case they're useful for the bad guys. I know it's somewhat inappropriate to ask for comments without revealing details. I suppose I'm asking for general responses then. :) Jeff C.

RFC: significantly reducing FPs on OB
by Jeff Chan 13 Jul '08

13 Jul '08

We can probably significantly reduce the false positives on ob.surbl.org, the SURBL list based on Outblaze's URI blacklist: http://www.surbl.org/lists.html#ob at the cost of some possibly minor false negatives. SpamAssassin has live (weekly?) statistics about the performance of their rules, including all SURBL lists, against their ham and spam corpora at their Rule QA site: http://ruleqa.spamassassin.org/ As you can see OB ranks significantly below the other SURBL lists, with much higher FP rates around 0.1% compared to 0.01% to 0.025% or so. (Note that the Rule QA site seems to have occasional glitches, so if the numbers seem out of range one week, check again later.) Should we make that change? Jeff C.

None of the lists will blacklist based solely on a user report. Each list is pretty different. Please report false positives to whitelist at our domain. Jeff C.

What does it take to be blacklisted?
by Ben Spencer 25 Jun '08

25 Jun '08

Ok...the subject is a bit misleading. Let me clarify a little bit... What does it take for a domain to end up on the multi.surbl.org list? Realizing that multi is made up of several different lists, it might not be clear cut as each might have their own rules and in some cases it is more complicated then just end user reports. Background: someone complained that they couldn't email us and it turns out they were blocked because of the multi.surbl.org list. In a response we received from them, they stated: One person has a software program that erroneously flagged <the domain> as spam. What I am trying to confirm is that none of the multi.surbl.org lists actually will block on a single incident report. Reading over the surbl.org site (haven't dig into the rules for each list just yet), the lists seem to sway towards safer (no listing) then sorry end of things.

are the lists working
by Peter Garcia 24 Mar '08

24 Mar '08

Hello I have joined this discussion forum today to ask if there is anything wrong with the multi.surbl.org list? We had been using this list successfully for almost 3 years now. Beginning about 3/15/08, we are no longer getting the same number of hits as we had before. Before 3/15 we routinely saw 6000 - 8000 SuRBL hits per day. Between 3/15 and today we were seeing less then 500 hits per day. This morning I switched our GWAVA to use black.uribl.com and am now seeing thousands of SuRBL hits. For test purposes I switched back to the multi.surbl.org but in 5 minutes didn't have any hits. Does anyone else have this problem? Thank you for any information. Peter Garcia

familiar with xml?

SURBL was great when it was running. It made me wonder if I should even run any other RBL's at all? This is off topic already but what is generally thought to have less overhead? It would seem to be that RBLs would but their effectiveness have really dropped with the use of massive botnets. Anyhow regarding my topic... something has changed in the usage of the lists and so my false positives has jumped. This is doug swallows plugin for Icewarp MerakMail. (the author has long since dropped support for this project) http://clip.drlinky.com/149606 I have altered the scope to not include the header (from the surblg list I was told to) and also to not scan the ip addresses but to no avail. I was getting false positives for test invites I was sending myself from linked in. I believe it is the way counting is performed that is messing things up a bit. From the looks of it a count of 1 is rejected, but 1 is added to everything anyway surbl_multi_count += 1 Appreciate any information Thank you KieranMullen
