cdbaby.com fp whitelisted
by Jeff Chan 18 Aug '04

18 Aug '04

cdbaby.com was on ws. I've whitelisted it along with a couple others: cdbaby.com hostbaby.com hitmedia.com This site claims to be the largest seller of independent musician CDs on the web: http://www.cdbaby.com/about > * In business, and thriving, since March 1998. We're the > largest seller of independent CDs on the web. [...] > Current Numbers: > > * 69,591 artists sell their CD at CD Baby. > * 1,129,709 CDs sold online to customers. > * $9,041,358.43 paid to artists. > > CD Baby Privacy Policy > > * We NEVER give or sell your personal info to any other > company - EVER! (No not even your email address!) > * Only the musician whose CD you buy will know who you are. > * If you don't even want the musician to know about you, > just say so at the bottom of your order form. There's no way this domain should ever have been listed, even if one of the artists using it DID spam. ws folks please trace this one back. We don't want more like this. Is anyone researching these before they get added? Even a cursory glance at their web page would show them to probably be legitimate. We really need to try to eliminate FPs or they will hurt the project. Jeff C.

Donation button added
by Jeff Chan 18 Aug '04

18 Aug '04

Raymond had suggested it while ago, but I've added a donation button to the SURBL site. Hope that's ok with everyone. (Of course it's all voluntary.) The account is my personal one since SURBL doesn't really have a business entity. We would use any donations to pay for bandwidth, hosting or other expenses that come up, perhaps including setting up an additional data server at a new location elsewhere in the world for some extra redundancy.

webpronews.com is an fp in ws. I've whitelisted it in SURBLs but please remove it from ws, and trace back the source. webpronews.com is in the bonded sender program and another domain belonging to ientry.com. I've separately asked ientry.com for a list of their domains to whitelist beyond: ientry.com ientry.net ientrymail.com webpronews.com Jeff C.

While I'm all for automation, but please be extremely careful. Take it from someone who knows, harvesting domains from scripts will lead to headaches. Like Jeff said, there is other encoding to deal with. URL poison. links that don't have http or www in them. ("Paste this into your browser......", btw SARE is working on that now.) I'm thinking the best way would be to take the actual SURBL code, and use it to rip out domains. But the SA code to unencode the email would be needed as well. Putting this in the email pipe would be best. If spam if not found in SURBL run SURBL extract + append to file :) --Chris

For what it is worth, if I turned off blocking at MTA level I would see a 33-40% increase in traffic. I don't want that. Every reject has a nice response saying where to email if you get blocked. I've got Delay_checks enabled. So I can override a listing. I've had to do it 3 times I think. All 3 times the customer was grateful I had informed then they were on a black list.

This thread is increasingly off-topic, but I am interested in the outcome of your analysis. On my end, it's worth noting that SpamAssassin with SURBLs rejects 8.6% of messages that passed through all of our blacklist and antivirus checks. I've been doing multi-blacklisting for a couple years. Currently mail must be on at least two of three of bl.spamcop.net, sbl-xbl.spamhaus.org, and list.dsbl.org to be rejected. I have seen false positives on Chinese universities, but not much else. Our 55x rejects always give specific reasons and an invitation to contact postmaster@brandeis. Here's my numbers from our primary MX over the last 10 days.

Fwd: [SURBL-Discuss] FP Pattern for sbl-xbl.spamhaus.org

Also depends on the volume of mail he processes. I'd be interested in if this is due to SBL or XBL hits. Both can produce FP's, but it brings up a debate as to what's an FP. If an IP has been found sending viruses or spam and is auto-listed by the XBL system (normally due to a compromised box), but that IP also sends non-bad email, it's not a false listing. We error on the side of stopping the 100,000 viruses being sent to users worldwide than to let the fewer legit emails pass. >However, I must admit, I'm drawing sweeping conclusions from very little >sampling of data. Therefore, don't take my word for it... If it's SBL, if he has a cousin in the Chinanet-CQ IP space, or in parts of Brazil Telecom's space, he'll probably see many more FPs as we do have large SBL listings. Also, if he gets email from people hosting on the cheap-spam-friendly networks like New Horizon, CET Networks or OC3, they get all IP space listed. >Rather, is this consistent with anyone else's experience with >sbl-xbl.spamhaus.org? The >reason I mention this is that, if my initial conclusions are true, there >would then be a strong argument for "holding" sbl-xbl.spamhaus.org blocked >mail and giving it a "second try" some hours later. He sure could, many people do greylist with DNSBLs. >Also, if this is true, >does anyone have a "feel" for exactly how long "bad" data stays on >sbl-xbl.spamhaus.org before it gets removed? No way to know. Most XBL listed IPs can be "self-removed", SBL mistakes that generate FPs are normally found out by us pretty quickly as either the blocked users or people who use us and like he, check their logs, let us know. >(Recognizing, of course, that >SpamHaus is probably the most reliable and respected free RBL in existence >and they rarely make mistakes in the first place). :-) >Any thoughts or suggestions? Has anyone examined their sbl-xbl.spamhaus.org >blocked messages lately? On large ISP type corpses, we still have a tiny fraction of true FPs. That being said, some places (with little volume or huge cheap bandwidth and lots of CPU) will just use SBL+XBL as a part of a SpamAssassin type formula. They won't toss on it being BL'd, but will want some other spammy trait to push it over the spam-score. >Rob McEwen

preparingforemergencies.co.uk false FP on OB
by Patrik Nilsson 15 Aug '04

15 Aug '04

preparingforemergencies.co.uk is listed on OB. It's a parody site that seem to be quite popular at the moment, getting forwarded in emails, mentioned in blogs, etc. I can't find any NANAS reports involving it. It is a quite recently registered domain though (26-Jul-2004) which might have contributed to it ending up on OB. Patrik
