Exactly, and do you have any idea how many of the lookups would be needed per day? I do! Enough to get the uribl dns ip doing the lookups, blocked from the whois servers. People running the whois servers don't really play nice with others. You need to approach them very carefully. APNIC is not going to be to helpful ;) --Chris >-----Original Message----- >From: Matthew Wilson [mailto:matthew@boomer.com] >Sent: Monday, May 09, 2005 1:29 PM >To: SURBL Discussion list >Subject: RE: [SURBL-Discuss] newly registered domains > > >I wasn't talking about doing huge numbers of whois lookups; I >was saying >cache the whois lookups in the a uribl dns zone, encoded using regex. > >> -----Original Message----- >> From: discuss-bounces(a)lists.surbl.org >> [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Chris Santerre >> Sent: Monday, May 09, 2005 9:20 AM >> To: 'SURBL Discussion list' >> Subject: RE: [SURBL-Discuss] newly registered domains >> >> Because they don't take to kindly to anyone doing tons of >> whois looksups an hour.

I wasn't talking about doing huge numbers of whois lookups; I was saying cache the whois lookups in the a uribl dns zone, encoded using regex. > -----Original Message----- > From: discuss-bounces(a)lists.surbl.org > [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Chris Santerre > Sent: Monday, May 09, 2005 9:20 AM > To: 'SURBL Discussion list' > Subject: RE: [SURBL-Discuss] newly registered domains > > Because they don't take to kindly to anyone doing tons of > whois looksups an hour.

Why not integrate a whois date lookup directly into SURBL or URIBL? Design an encoding system whereby suspectedspammydomain.spammertld.dr.surbl.org (or uribl.com) would return the date somehow regex encoded in the IP address. Then write a nice SA rule that decodes it, also using regex. Are there any regex geniuses out there that could encode a date in an IP address? -Matthew > Well this has been brought up before.

Well this has been brought up before. It is a very good idea, however difficult to implement. Unfortunetly the date returned by a whois querey comes in a wide variety of flavors. We (SARE) thought we had all of the returned date codes figured out. Nope. New ones still keep coming. uribl.com has some ideas on how to attack this very issue, but not sure it is worth it yet. In short, it would be wonderful to start doing whois lookups for every domain in an email. Lots of things could be flagged off of it. Think of a sort of baysien whois DB.

When you say several times an hour, does that mean weekends and holidays also? /E. -----Original Message----- From: discuss-bounces(a)lists.surbl.org [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Jeff Chan Sent: Sunday, May 08, 2005 11:01 AM To: SURBL Discussion list Subject: Re: [SURBL-Discuss] multi.surbl.org.rbldnsd Update Times On Sunday, May 8, 2005, 7:09:11 AM, Eric Smith wrote: > I'm sure this is dependent on the mirror we are pulling the zone from, but > how often is the source zone updated, and should we expect that mirrors > update on a regular schedule around the clock?

newly registered domains
by Matthew Wilson 09 May '05

09 May '05

Does anyone know of a SA rule to check how recently a domain name has been registered? The various uri lookups catch the vast majority of spammy urls during the day, but from 2-5 a.m. CST, my servers get hit with tons of spam with urls that aren't in SURBL yet. All of the domains are newly registered domains (registered in the past week or so). I know that the SARE ninjas have some private tools to do this kind of lookup for their feeds and manual lookups, but I'm wondering if this kind of thing could be worked directly into a SA rule. Thanks, Matthew

multi.surbl.org.rbldnsd Update Times
by Smith, Eric 08 May '05

I'm sure this is dependent on the mirror we are pulling the zone from, but how often is the source zone updated, and should we expect that mirrors update on a regular schedule around the clock? What I'm getting at is we are monitoring file changes to the zone file to ensure it's updating often, but as of Friday we have received no updates (I'm guessing because it doesn't get updated on the weekends). Is my assumption correct? Does the schedule vary by mirror? If so is there a mirror that anyone knows the replication interval for? If not Jeff do you know the schedule requirements for a site to become a mirror so we can base monitoring off this schedule? Any input is greatly appreciated. Thanks, Eric

XBL actually, very strange, I will check and follow up regarding it. /E. -----Original Message----- From: discuss-bounces(a)lists.surbl.org [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Jeff Chan Sent: Friday, May 06, 2005 11:34 PM To: SURBL Discussion list Subject: Re: [SURBL-Discuss] SURBL Content On Friday, May 6, 2005, 5:59:15 PM, Eric Smith wrote: > This morning we received a huge blast from a spammer that spamhaus.org > identified properly but multi.surbl.org.rbldnsd didn't :( Just checking > though :) > Eric When you say spamhaus.org, which list are you referring to, XBL or SBL? Because one of the new lists we're experimenting with, xu.surbl.org, gets data from CBL spamtrap URI hits. CBL feeds into XBL, and some of the XBL senders probably end up in SBL also. Next time you see one like this, if you check it using the SURBL checker: http://www.rulesemporium.com/cgi-bin/uribl.cgi it would be interesting to to hear if it hits the preliminary version of the XS data.

This morning we received a huge blast from a spammer that spamhaus.org identified properly but multi.surbl.org.rbldnsd didn't :( Just checking though :) Eric -----Original Message----- From: discuss-bounces(a)lists.surbl.org [mailto:discuss-bounces@lists.surbl.org] On Behalf Of Jeff Chan Sent: Friday, May 06, 2005 8:03 PM To: discuss(a)lists.surbl.org Subject: Re: [SURBL-Discuss] SURBL Content On Friday, May 6, 2005, 10:57:25 AM, Eric Smith wrote: > Quick question regarding multi.surbl.org.rbldnsd; the list of content for > this file (i.e. sc.surbl.org, ws.surbl.org, etc) on the surbl.org website is > all inclusive correct?
