Garbage in… garbage out

Ken Magill (hereafter known as Mr. Stupid Poopypants) has a follow up article today on his article from last week about the Obama campaign’s mailing practices. While poking Dylan a bit, his message is that marketers really need to look harder at double opt-in.

All these things can and do go wrong with double opt-in, but the risks of not using it have simply become too great. For one thing, if a marketer gets blacklisted by, say, Spamhaus, and the mailer is not using double opt-in, the folks at Spamhaus will force the issue.
On the plus side, marketers using double opt-in don’t get blacklisted by Spamhaus because they never hit Spamhaus’s traps—fake e-mail addresses set up to catch spammers.
Also, fake signups are nothing to get worked up about. They are simply a fact of e-mail list building that the marketer must guard against or accept the inevitable consequences. It is solely up to mailers to keep their lists clean, and no one else.

Data verification is a necessary and critical bit of email marketing on today’s internet. For many marketers, the only solution may be to move to double opt-in.

Yahoo and Spamhaus

Yahoo has updated and modified their postmaster pages. They have also put a lot of work into clarifying their response codes. The changes should help senders identify and troubleshoot problems without relying on individual help from Yahoo.
There is one major change that deserves its own discussion. Yahoo is now using the SBL, XBL and PBL to block connections from listed IP addresses. These are public blocklists run by Spamhaus. Each of them targets a different type of spam source.
The SBL is the blocklist that addresses fixed spam sources. To get listed on the SBL, a sender is sending email to people who have never requested it. Typically, this involves email sent to an address that has not opted in to the email. These addresses, known as spamtraps, are used as sentinel addresses. Any mail sent to them is, by definition, not opt-in. These addresses are never signed up to any email address lists by the person who owns the email address. Spamtraps can get onto a mailing list in a number of different ways, but none of them involve the owner of the address giving the sender permission to email them.
Additionally, the SBL will list spam gangs and spam supporters. Spam supporters include networks that provide services to spammers and do not take prompt action to remove the spammers from their services.
The XBL is a list of IP addresses which appear to be infected with trojans or spamware or can be used by hackers to send spam (open proxies or open relays). This list includes both the CBL and the NJABL open proxy list. The CBL list machines which appear to be infected with spamware or trojans. The CBL works passively, looking only at those machines which actively make connections to CBL detectors. NJABL lists machines that are open proxies and open relays.
The Policy Block List (PBL) is Spamhaus’ newest list. Spamhaus describes this list as

Spamhaus files for dismissal of e360 case

Spamhaus filed a motion today asking the judge to dismiss the e360 v. Spamhaus case for contempt. Mickey, as usual, has the docs up.
I have not posted much on the case recently, as there was only legal wrangling about discovery going on. The biggest problem being that e360 has dragged their feet, stalled and avoided discovery for the last 8 months. They have missed deadlines, turned over incomplete documents and ignored depositions. Since I last wrote about this case, discovery has been extended multiple times, the judge has compelled e360 to turn over docs and information and he sanctioned e360 for their failures to comply.
From my perspective, Spamhaus’ lawyers have been setting the stage for this motion for the last 4 – 5 months. Their interactions with e360’s lawyers, their motions to compel and their motion for sanctions have all formed a narrative of how e360 is stonewalling discovery.
This particular motion is only about 8 pages long, but references a 125 page exhibit. The very large exhibit is mostly documents that have been published before in the “Motion for Various relief due to Persistent Discovery Defaults” filed in July.
In the July motion, Spamhaus’ lawyers detail their repeated efforts to get discovery from e360, and the utter lack of cooperation. One of my favorite bits is that e360 responded (weeks late) to some of the initial interrogatories with (paraphrased), “It is too hard to write all this down, but we will tell you about it in the depositions.” My understanding of the law is that this is, in and of itself, a bit of a no-no. What really puts the icing on the cake, though, is that e360 then skipped 2 properly noticed depositions. They just did not appear, thus making their answers to the interrogatories utterly meaningless.
Spamhaus requested that the Judge impose sanctions on e360 for failing to appear at 2 depositions, not complying with the judge’s previous orders and generally being unable to actually produce any documentation that is complete or on time. Even better, when e360 did manage to produce a thumb drive it contained multiple email conversations between Mr. Linhardt and his lead counsel. This little oops happened because no one at the law firm bothered to actually examine any of the files before handing over the thumb drive. In fact, they only became aware of their error when opposing counsel notified them of the files. When e360 asked for the information back, Spamhaus’ lawyers refused pointing out that they handed over all the information willingly and that their failure to actually examine the files does not constitute an inadvertent disclosure.
The judge did sanction e360, although not with the severity that Spamhaus’ lawyers requested. He also ordered full discovery and documents turned over by August 15th. Based on my reading of the transcript (exhibit 4) the Judge sounds like he is tired of having to tell the e360 lawyers to do their jobs. The judge lectured e360 on their failure to get thing resovled.

Update on Yahoo and the PBL

Last week I requested details about Yahoo rejections for IPs pointing to the PBL when the IP was not on the PBL. A blog reader did provide me with extremely useful logs documenting the problem. Thank you!
Based on my examination of the logs, this appears to be a problem only on some of the Yahoo! MXs. In fact, in the logs I was sent, the email was rejected from 2 machines and then eventually accepted by a third.
I have forwarded those logs onto Yahoo who are looking into the issue. I have also talked with one of the Spamhaus volunteers and Spamhaus is aware of the issue as well.
The right people are looking at the issue and Spamhaus and Yahoo are both working on fixing this.
Thanks for the reports and for the logs.
