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.

PBL and Yahoo

A few days ago I posted about Yahoo using the Spamhaus lists. In the comments of that post there have been multiple reports of mail being bounced from Yahoo with a reason of “on the PBL” but the IP was not on the PBL.
I am happy to look into this for people. I’m sure neither Spamhaus nor Yahoo want to be incorrectly rejecting email. To do this, though, I need the rejection message from Yahoo, the IP the mail was sent from and when it happened. Feel free to email the information to laura at wordtothewise.com.

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.
