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.

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

Changes at AOL Postmaster desk

The recent layoffs at AOL did affect the AOL Postmaster desk, and information I have received is that there was significant loss. As a result of the staff decrease, some changes have been made to the whitelisting and FBL processes. In order for a FBL to be approved it must meet the new FBL guidelines. In a nutshell, anyone wanting to get a FBL from AOL must meet ONE of the following criteria.

They’re not blocking you because they hate you.

Really. They’re blocking you because you’re doing something that is triggering their blocking mechanisms.
This has happened over and over and over again. Some political or activist website sends out an email that gets blocked by some large ISP and the political site turns it into a giant crisis that means the ISP hates them or is trying to shut them up or is trying to silence their message.
Except that’s not what is going on. The folks at the large ISPs who handle blocking and incoming mail are incredibly smart and conscientious . They take their jobs seriously. They, both personally and corporately, want their customers (the end recipients) to receive the email they want. Additionally, they do not want to deliver mail that the recipients did not ask to receive.
In almost no cases is the block a particular activist site encounters a result of the ISP not liking the content of the email. If an activist site is being blocked it’s due to complaints or reputation or something that ISPs measure and block on. Some person at the ISP didn’t read your email, decide they didn’t like what you had to say and then block that email. That email was blocked because something related to that email triggered the thresholds for blocking.
Of course, as with everything online, there are caveats. In this case it’s that the above statements really only hold true for large ISPs in free countries. There are some countries in the world that do block email based on content, and that is dictated by the government. Likewise, some small ISPs will block based on the guy in charge not liking the email.
Generally, though, if an activist site is being blocked by a large ISP in the US or other free countries it is because their mailings are somehow not complying with that ISPs standards. Instead of starting an email campaign or blog campaign to shame the ISP for suppressing speech, it is much more productive to actually contact the ISP in question and find out what went wrong.
