Spamhaus and Gmail

Today’s been chock full of phone calls and dealing with clients, but I did happen to notice a bunch of people having small herds of cows because Spamhaus listed www.gmail.com on the SBL.
“SPAMHAUS BLOCKS GOOGLE!!!” the headlines scream.
My own opinion is that Google doesn’t do enough to police their network and their users, and that a SBL listing isn’t exactly a false positive or Spamhaus overreaching. In this case, though, the headlines and the original article didn’t actually get the story right.
Spamhaus blocked a range of IP addresses that are owned by Google that included the IP for www.gmail.com. This range of IP addresses did not include the gmail outgoing mailservers.
Spamhaus says

Some Google-owned server IPs hosting severe malicious spam problems – specifically Google’s “Google Docs” service – do get rightly listed in the Spamhaus SBL when Google does not take action fast enough to stop the serving of malicious sites via Google Docs. Such listings act as pointers to the abused resource but do not in any way affect Google’s Gmail service or any Google outbound mail service.

Spamhaus goes on to talk about the responsibility providers have to police their userbase and the fact that large providers who are not policing their users are cost shifting to the rest of us.

We at Spamhaus surely understand the challenges that the cloud service providers face. These problems are not easy to solve and the scale and complexity of the systems involved certainly does not make things easier. What we are puzzled by is how the rest of the internet has to keep carrying the burden of this abuse. The companies that host these services all without exception make hundreds of millions of dollars each year. They employ some of the best and brightest engineers. Surely they can spend a little of their immense resources on making the internet they rely on for their business, a better and safer place.

Unfortunately, Google doesn’t seem to see any value in policing their customers and users. If they can’t make a buck at it, then it doesn’t get done. And if Google’s costs of doing business are shifted to other companies, so much the better. Good for Spamhaus for standing up and pointedly telling Google they can’t keep supporting spam and spammers.

“If you do stupid things, you’re going to get blocked,” says Jigsaw CEO Jim Fowler in an interview with Ken Magill earlier this week.
Jigsaw is a company that rewards members to input their valuable business contacts. Once the addresses are input into Jigsaw, they are sold to anyone who wants them. Jigsaw gets the money, the people providing information get… something, the people who provided business cards to Jigsaw members get spammed and the people who downloaded the lists get to deal with a delivery mess. Sounds like a lose for everyone but Jigsaw.
Except that now Jigsaw is listed on the SBL for spam support services. Well, that’s going to cause some business challenges, particularly given how many companies use the SBL as part of their filtering scheme.
It’s hard to think of a situation where I would appreciate someone I gave a business card to providing my information to a site that then turns around and lets anyone download it to send email to. I know, I know, there are a million companies out there I’ve never heard of that have The Product that will Solve All my Problems. But, really, I don’t want them in my work mailbox. The address I give out on my business cards is, for, y’know, people to contact me about what I’m selling or to contact me about things they’ve already purchased from me. That address is not for people to market to. I have other addresses for vendors, and even potential vendors, to contact me.
Jigsaw clearly facilitates spam to businesses by collecting email addresses and then selling them on. This is a drain on small businesses who now have inboxes full of valuable offers to wade through. Perhaps their stint on the SBL will make them reconsider their spam support services.

Alphabetical spammers

There have been a couple posts recently about a paper presented at the Fifth Conference on Email and Spam (CEAS). The paper showed how addresses beginning with different letters get different volumes of spam.
But this post is not really about the paper, although it is an interesting academic review of spam, it is more about a memory that the discussions triggered.
Long ago I was handling the abuse desk at the very large network provider. This was in the days before Feedback loops, so every complaint was an actual forwarded email from a recipient. Generally, we saw a couple dozen complaints about any individual spam problem. Not a huge volume by any means, but that meant that any volume of complaints was significant.
One afternoon I started seeing a spike in complaints about a customer who never received complaints before. I started looking a little deeper and discovered we had around 50 complaints about this mailing, many from people I knew, and all from individuals at domains that started with A. This was one of the few times we actually pulled the plug in the middle of a mailing.
I still remember going to my boss suggesting this was something to take action on now because we had over 50 complaints and they were still in the A‘s! The customer was mortified that the guaranteed opt-in list they purchased was so bad and promised never to spam again.
Have a good weekend everyone.
