by sheirling 20 Nov '08

Hi, We've submitted a removal request for our domain skyquestcom.com using LOOKUP page in surbl.com (filled in the complete form and the response page show "your request has been received") Yet our domain is still in the blacklist. May I know usually how long will it take for our domain to be removed from the list? Will there be any email notification? Thank you for your help. Regards, sheirling.

I would say anyone who is thinking of not using it due to policy changes should discuss this with them OFFLIST. I believe this is not ment to hinder people using it, or even become filthy rich. Just to keep the darn thing running :) But thats just my opinion. Jeff is good people ;) --Chris

All large rsync users would be asked to pay, but there would be a 90 day grace period. Arnie can probably provide more details: Arnie Bjorklund MXTools http://www.mxtools.com/ 1-866-931-9228 His email address is arnieb at his domain above, and he's also seeing this since he's on the list.

At-- SURBL usage policy: http://www.surbl.org/usage-policy.html I get very different pricing depending whether I input 80,000 users or 80000 users (same number, no comma). Number of messages does not affect it. At the price for 80,000 (sic) I have no objection at all. At the other price I'll really have to analyze how much we block with it. I'm not sure what conclusion I will reach. Joseph Brennan Lead Email Systems Engineer Columbia University Information Technology

Stats wanted
by Jeff Chan 20 Oct '08

20 Oct '08

Hi All, SURBL is looking for statistics about what portion of unsolicited our lists are detecting (ideally in large mail flows). An overall number would be ideal, as in what fraction of total unsolicited messages are caught by any SURBL list. One possible way to measure this from SpamAssassin-processed messages would be to count the messages marked as spam that had 'SURBL' in their scores versus the ones that didn't have a SURBL rule hit. The ratio would be the spams with SURBL hits divided by total number of spams. Another way would be to count the SURBL hits from an MTA milter, but to have the meaningful denominator, one would need a count of the total spams, which a simple SURBL-only milter would not be able to provide. Something else, or a more sophisticated milter would need to count the total spams in order to get the denominator. Ideally the results would be after MTA blocking with a major sender blacklist like zen.spamhaus.org. Please let us know whether a sender blacklist is used in the MTA or not. Any results would be greatly appreciated. Cheers, Jeff C.

I should have added, here is a SpamAssassin meta rule that may show how many messages hit any surbl rule: meta URIBL_META_SURBL_ANY (URIBL_AB_SURBL || \ URIBL_JP_SURBL || URIBL_OB_SURBL || URIBL_PH_SURBL || \ URIBL_SC_SURBL || URIBL_WS_SURBL) score URIBL_META_SURBL_ANY 0.01 (For however the line wraps should be handled.)

URI BL responses, always loopback network?
by Ron Guerin 06 Aug '08

06 Aug '08

Hello again, I posted here once before I believe on the subject of URL shorteners. I am the operator author of the GPL software known as TightURL, and operator of the .com of the same name where there is a public installation of this software. I was supposed to come back with some kind of response about checking URL submissions at submission time vs. re-checking later, but various things in life intervened, and I have yet to implement anything to track how many URLs I reject at submission time, but I am pleased to report that re-checking previously accepted URLs has clearly been a success. I am presently rechecking all my URLs every 6 hours *if* they meet the following conditions: * Is not already blocked in my database * Was added within a window period (7 days) -or- * Has recent activity and more than a threshold of hits recorded Using this formula, I've been blocking URLs that were submitted over a year prior to blocking them, along with many recent submissions. I have not added the capability to unblock them later, largely because visual inspection of the blocked URLs gives me a pretty good feeling they'll be blocked again sooner or later. I may have to do something about that, but I'm not seeing the need right now. Anyway,... today's question pertains to people who are mucking around in their DNS resolution, or have DNS providers that are falsifying DNS responses in order to generate ad income from typing errors in people's browsers. I recently concluded some support for a new user whose every URL submission appeared to be listed in both SURBL and URIBL, which my code checks to see if the URL should be rejected. This user was somehow getting his own IP address returned to him any time the true response was really NXDOMAIN. This was some local thing on his end, but I presume the same problem exists if your DNS provider is tampering with the responses, except in that case you'd get some IP address from the public IP space that misdirects you to some "helpful" site if you happen to be using a web browser. My workaround for this problem was to check to see if the first 4 characters of the response are "127." Every BL or URI BL I know about returns a response somewhere in the range of 127.0.0.0 - 127.0.0.255, unless I'm mistaken. While I guess this still leaves open the possibility for false-positives on my users end if they make use of both loopback network hosts and their DNS responses have been tampered with, what I wanted to know was if anyone knows of a BL or URI BL that returns or plans on returning something other than a loopback address as a positive response to a lookup? - Ron

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

Re: [SURBL-Discuss] RFC: significantly reducing FPs on OB

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.
