Updating SenderID records for Microsoft

In the past, bulk senders who wanted Microsoft to check SenderID had to email information to a special Microsoft address. Microsoft would then cache the senderID data from the sender’s DNS records and verify incoming email.
Microsoft has simplified the process and now has a webform to submit the data.

In order to submit your information you will need a contact email address, the domains that you want to add and the SPF records of those domains.

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.

Predictions for 2008

I did not have a lot of predictions for what will happen with email at the beginning of the year so I did not do a traditional beginning of the year post. Over the last 3 – 4 weeks, though, I have noticed some things that I think show where the industry is going.
Authentication. In January two announcements happened that lead me to believe most legitimate mail will be DK/DKIM signed by the end of the year. AOTA announced that approximately 50% of all email was currently authenticated. They did not separate out SPF/SenderID authentication from DK/DKIM authentication, but this still suggests email authentication is being widely adopted. AOL announced they will be checking DKIM on their inbound mail. I expect more and more email will be DKIM signed in response to this announcement.
Filtering. The end of 2007 marked a steady uptick in mail being filtered or blocked by recipient domains. I expect this trend to continue throughout 2008. Recipient domains are rolling out new technology to measure complaints, evaluate reputation and monitor unwanted email in ways that tease out the bad actors from the good. This means more bad and borderline email will be blocked. Over the short term, I expect to see more good email blocked, too, but expect this will resolve itself by Q2/Q3.
Sender Improvements. As the ISPs get better at filtering, I expect that many borderline senders will discover they cannot continue to have sloppy subscription practices and still get their mail delivered. Improved authentication and better filtering let ISPs pin-point blocks. Instead of having to block by IP or by domain, they can block only some mail from a domain, or only some mail from an IP. There are a number of senders who are sending mail that users do not want mixed with mail that recipients do want. Right now, if there is more mail that recipients want in that mix, then ISPs let the mail through. This will not continue to happen through 2008. Senders will need to send mail users actively want in order to see good delivery.
Less is more. A lot of other email bloggers have talked about this, and I will echo their predictions. Less email is more. Send relevant mail that your customers want. Target, target, target. Good mailers will not send offers to their entire database, instead they will send mail to a select portion of their database.
Feedback loops. Use of feedback loops by recipient domains will continue to grow.
Mobile email. More recipients will be receiving email on mobile devices.

Changes at RoadRunner

I’ve been hearing rumors that some *.rr.com domains have been bouncing all mail sent to them. Those domains belong to customers that were moved to Comcast as part of the RoadRunner / Comcast / Adelphia purchase and customer swap. As a courtesy, RoadRunner forwarded mail to comcast for those former RoadRunner customers, but have ceased to do so.
Mail to any address in the following *.rr.com domains will no longer be delivered.
jam.rr.com
midsouth.rr.com
mn.rr.com
se.rr.com
sport.rr.com
swfla.rr.com
ucwphilly.rr.com
houston.rr.com
These addresses should be removed from your lists. These users now have Comcast addresses. You cannot just substitute the Comcast domain for the RoadRunner domain as users were required to choose new localparts. That means bobjones@houston.rr.com may not be, and probably is not, bobjones@comcast.
