Hi! Our favorite pill spammers also try to get around SURBL now. I dont want to end up making SA rulesets for this, any suggestions ? ns3.airmaramba.biz ns3.avk29.biz The same crap... But, with less SA hits now, since its not touched by SURBL.

Re: [SURBL-Zones] Lowering TTLs

OK I'm changing the TTLs on all tue SURBL lists to 25 minutes which is a midway point between the 20 minutes I was going to try for SC and the 30 minutes we proposed for the rest of the lists. 25 minutes is also a good sampling frequency to capture data that has a 1 hour characteristic frequency. This is mainly an experiment to see what effect it has on DNS traffic. If the traffic on SC is not a lot lower, I'll change it back to 10 minutes. If the traffic on the other lists is not a lot higher, I'll leave it at 25 minutes. Jeff C. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/

I can't tell where you are on this subject now Jeff :) Are you saying , that if we get really good data like what was in my original post, and we keep the data in the 90th percentile area, then we might possibly be able to list the IP hosts and have SURBL check against it? If so..I'm up for that. Granted it would take a little more research then just a domain listing, but I think the benefits are very good. Especially if we keep it only high ranking IP offenders. I mean, we may add less then 50 IPs a year? Just the really nasty spammers. Anyway, its been a great discussion. If we've learned anything in the last 24 hours, its that the Patriots defense needs some work against the run game ;) --Chris (Go Tom Brady!)

I think this would hit more FPs then listing the IP! Am I wrong there! I would never list the name server, as they may be hosting for much more then just a spammer. That number is sure to be greater then a virtual hosts number for an IP. Maybe I'm missing something key? You won't see me ever add an NS IP to SURBL. Now that I've had time to think of it. --Chris

It seems to me that Jeff is talking about a way of implementing what Chris is talking about. If not, then it still seems like a great compromise! I love the idea!

If you're talking about adding resolved IP addresses to SURBLs, no we're not going to do that. :-( What I'm talking about is an internal process where we keep track of resolved IP addresses and use that to add new domains to SURBLs sooner if they resolve to a similar IP range (probably /24s). We would use the resolved IP addresses to add domains to sc.surbl.org and possibly other lists sooner. Most would probably get added on the first report. :-) http://www.surbl.org/faq.html#numbered Jeff C.

If it helps, I agree with Chris. One point to note: Virtual hosters can't use IP addresses in their URLs, because the web server needs a http host header to differentiate between all the possible virtual hosted sites. However, it really wouldn't be difficult to have the SURBL URI detection algorithm find dotted quad URLs, and store these in the SURBL database just like any other domain name... -Matthew -----Original Message----- From: discuss-bounces(a)lists.surbl.org [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Chris Santerre Sent: Thursday, September 09, 2004 4:19 PM To: 'Raymond Dijkxhoorn'; Alex Broens Cc: SURBL Discussion list (E-mail); Spamassassin-Talk (E-mail); users-return-15498-sa-list=alexb.ch(a)spamassassin.apache.org Subject: [SURBL-Discuss] RE: Start an IP list to block? >-----Original Message----- >From: Raymond Dijkxhoorn [mailto:raymond@prolocation.net] >Sent: Thursday, September 09, 2004 5:10 PM >To: Alex Broens >Cc: users-return-15498-sa-list=alexb.ch(a)spamassassin.apache.org; SURBL >Discussion list (E-mail); Spamassassin-Talk (E-mail) >Subject: Re: Start an IP list to block? > > >Hi! > >> Chris, Raymond , >> >> I went thru a random few of these and they're were listed at >Spamhaus. >> Using spamhaus at SMTP level or SA doing RBL lookups would >have caught and >> stopped them...

They may be listed, but for mail, not hosting. They use other IPs to send, and keep the host on their IPs. SOme of the bigger spammers are saying "Screw SURBL, I've got enough dough to get a new domain for every run, and it still remains profitible." To which we have 2 replies: 1) Those registers are going to feel some rath soon from the antispam community. 2) We gonna mark the IP, you silly little monkeys! I think the code should be added into the SURBL code. It would need to be a patch for SA 3.0 as it is prbly too late for it to go in now. But it should be simple to grab the IP of the 20 random URL domains and match against SURBL as well. Then they can purchase as many domains as they like, won't matter a bit. --Chris _______________________________________________ Discuss mailing list Discuss(a)lists.surbl.org http://lists.surbl.org/mailman/listinfo/discuss
