Delisting at ATT

ATT used to have a webform to use to request delisting. I’ve heard reports over the last few months that the form isn’t working. This week, the website hosting the form disappeared. I don’t know for sure, but this looks like this is either deliberate or there’s just no one in charge of the site and it got lost.
ATT provides an email address for delisting, too. Unfortunately, I’m also hearing they’re not responding to that address. There are two possible reasons. One, they’ve never answered and they just delist or not depending on stats. Two, they’re not monitoring that address, either.
In any case, the delisting isn’t working and I don’t know when it will be. I know some people have contacted ATT reps, so they are aware of the current issues. More as I find out.

Do system administrators have too much power?

Yesterday, Laura brought a thread from last week to my attention, and the old-school ISP admin and mail geek in me felt the need to jump up and say something in response to Paul’s comment. My text here is all my own, and is based upon personal experience as well as those of my friends. That said, I’m not speaking on their behalf, either. 🙂
I found Paul’s use of the word ‘SysAdmin’ to be a mighty wide (and — in my experience — probably incorrect) brush to be painting with, particularly when referring to operations at ISPs with any significant number of mailboxes. My fundamental opposition to use of the term comes down to this: It’s no longer 1998.
The sort of rogue (or perhaps ‘maverick’) behavior to which you refer absolutely used to be a thing, back when a clean 56k dial-up connection was the stuff of dreams and any ISP that had gone through the trouble to figure out how to get past the 64k user limit in the UNIX password file was considered both large and technically competent. Outside of a few edge cases, I don’t know many system administrators these days who are able to (whether by policy or by access controls) — much less want to — make such unilateral deliverability decisions.
While specialization may be for insects, it’s also inevitable whenever a system grows past a certain point. When I started in the field, there were entire ISPs that were one-man shows (at least on the technical side). This simply doesn’t scale. Eventually, you start breaking things up into departments, then into services, then teams assigned to services, then parts of services assigned to teams, and back up the other side of the mountain, until you end up with a whole department whose job it is to run one component of one service.
For instance, let’s take inbound (just inbound) email. It’s not uncommon for a large ISP to have several technical teams responsible for the processing of mail being sent to their users:

Asking for help with a blocklist

There are often questions arising about how to go about getting off a particular blocklist. A few years ago I led the MAAWG effort to document what to if if you were On a Blocklist (pdf link). That document was aimed primarily at MAAWG members and deliverability experts with working knowledge of blocklists. I think, even now, it’s a good background on how to deal with a listing and mail being blocked.

There have been discussions on multiple mailing lists over the last week or so about how to deal with listings at different blocklists. Many folks on these lists have extensive experience, so these are good places to ask. With that being said, a lot of the requests lack sufficient details to help.
So, if you’re ever on a blocklist and want some help from a mailing list about the problem, here’s a short guide for how to ask for help.

Email filtering: not going away.

VirusBlockI don’t do a whole lot of filtering of comments here. There are a couple people who are moderated, but generally if the comments contribute to a discussion they get to be posted. I do get the occasional angry or incoherent comment. And sometimes I get a comment that is triggers me to write an entire blog post pointing out the problems with the comment.
Today a comment from Joe King showed up for The Myth of the Low Complaint Rate.
