Default URIBL.com - Do Not Use Their Email Black Lists

URIBL.com is a site that maintains an Email Blacklist and this is from their About Us page:

Quote:
"This lists contains domain names belonging to and used by spammers, including but not restricted to those that appear in URIs found in SPAM. This list has a goal of zero False Positives. This zone rebuilds frequently as new data is added."
Yes that's correct, domains found "in" spam are added to URIBL's email blacklist. Think about this for a second, i get your business email address and compose a spam email saying "Buy Male Enlargement Potions contact you@yourbusiness.com" in the message body.

I send it to my other email account, then report it to URIBL.com and your whole @yourbusiness.com mail accounts are blacklisted costing you thousands in revenue due to people filtering their mail based on URIBL.

Houston we have a problem!

You can be the most legitimate business under the sun, one that is totally against spam and does their best to fight it themselves. You can have a simple site MyFamilyName.com just for your family to share photos, it doesn't matter to URIBL.com they will list your whole domain on their spam blacklist due to someone who does not like you that files a fake complaint.

URIBL does not need to justify their actions, and it's impossible to show them proof you did not send an email which leaves the option of registering on their site and "sucking up" to hopefully get removed.

Remember, the email does NOT need to come from your domain and your server does not even need to have mail capabilities to be labelled an email spammer by URIBL. Your domain simply needs to be typed in to the message body of an email and reported to them as spam which anyone can do to you.

I hate spam as much as the next person, but the last thing we need is "Blacklist Cowboys" costing people thousands of dollars like URIBL.com does.

So if you need to mail Blacklist to filter your mail against, i highly recommend DO NOT use the services of URIBL.com

The other ironic thing, when i registered on URIBL their confirmation email ended up in my junk folder. Quite fitting really.

Yup, I agree completely. They even have blacklisted bellsouth... I was using them for weeks until the many complaints form my customers that were not receiving emails from bellsouth accounts made me realize about it. I no longer use this IBL on my servers.

Default I am one of those bussiness, is there anything we can do?

Hey,

I recently started a marketing business dealing only with customer based mailing lists. no SPAM.
However, I get listed on URIBL every week.

Talking to them and requesting a removal didn't help.

Is there anything I CAN do not to be listed on URIBL everytime?

Any direction will be greatly appreciated ..

Thanks!

Default Curious about your situations...

I'm good friends with some of the guys who run uribl.com and, while I do find myself disagreeing with some of their listings on occassion, overall I think they do a very good job.

True, their listing criteria differs with mine sometimes (I manage some anti-spam blacklists as well). And I do understand that blacklists make mistakes sometimes. But I don't find uribl.com to be run with the inaccuracies and tactics as has been described on this thread.

But I'm willing to listen, and will use whatever feedback you provide as good lessons for my running of my own uribl (using that term generically) as well as my own ip blacklist.

So please get specific. What are some of the items that uribl wrongly blacklisted?

Hello Rob, thanks for dropping by.

I'm sorry you feel there's inaccuracies in the thread, everything i've posted is factual so maybe you mean the blocking of Bellsouth posted by LINUXADDICT? If so i have no idea about that one, i'm not from the US and i know very little about Bellsouth.

I started a thread over on WHT about URIBL and you actually made a few posts on it i remember your name. I am all for anti-spam solutions, i own about 80 sites and get tired of dealing with it in emails, forum posts, blog comments, contact forms etc on a daily basis.

URIBL just doesn't seem like a good solution, it's only caused me problems and cost me money which anti-spam solutions should avoid doing to innocent people at all costs. Here is an interesting one which effected one of my domains, it was a short URL service that got listed.

Now, the site had a strict TOS in place, a contact/report violation link on every page encouraging anyone who believes a URL was being abused to submit it for removal. From the ones that did get submitted, i think 6 hours was the longest it took to for a URL to be disabled. The short URL's didn't cloak, they showed the real destination URL, there was no email associated with the service just the contact form input.

Would you blacklist the whole domain and effect over a hundred thousand innocent users of the service?

Note, this isn't the blacklisting that had the biggest impact to me personally but it's the one i'm most curious about.

Default solution: use uribl.com for scoring instead of blocking

Don't be sorry. And I didn't meant to imply that I think that you are all wrong. I'd just like to see more details so that I can learn more about this. And I simply said that this didn't match my experience with uribl.com

I think when one is critical of something or someone, their message ought to contain hard facts to back up their claims. I think that is very fair.

Generally, I shy away from listing even abused shortening URL services on ivmURI. But short URL services are tough. Some of them have ratios where for every one "innocent" usage, there are literally thousands of spam uses. At this time, no URL shortening service is going to work unless/until they start checking the domains the URLs resolve to against surbl/uribl/ivmURI--and disabling any such redirects if/when the domain it resolves to is blacklisted. Otherwise, the incentive for spammers to abuse the service is too high for the system to be anything but a spam factory.

I believe that uribl.com is purposely a little more aggressive than either surbl or ivmURI. I think they are this way unappologetically. But, at the same time, they themselves state that their lists are best used for scoring instead of outright blocking. I recall their admins saying that they ought to be scored a point or two below threshhold.

While they don't seem to state this on their web site, their example Spam Assassin rules they provide there *do* score in that manner!

But the problem is that many don't use uribl in that manner and just go ahead and outright block on uribl.com

Getting back to your shortening URL example... in a case where the service is severly abused... where the ratio of spam-to-ham is 100 to 1. Then using URIBL for scoring (instead of outright blocking) should put most of those spams "over the top", while not blocking most legitimate e-mails where that url shortening service was used.

At least, that is how this is suppose to work. But when spam filters use uribl.com for blocking instead of scoring, this leads to too many FPs.
