In early September, I posted about a survey being done by Jan Schaumann regarding how sysadmins viewed their ethical obligations with regard to users. The results of this have now been published by Jan. He’s also shared his talk and slides on the data.
Well worth a look through the data. I took a quick run through of his talk and it looked interesting and is definitely going on my to-read list.
Jan Schaumann is putting together a talk on ethics in as related to folks managing internet operations. He has a survey and is looking for folks who wrangle the machines that run the internet. I’m copying his post, with permission, due to a slightly NSFW image on his announcement.
Read MoreYesterday, 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:
Earlier this month Google announced a new set of tools for senders at their Postmaster Tools site. To get into the site you need to login to Google, but they also have a handy support page that doesn’t require a login for folks who want to see what the page is about.
We did register, but don’t send enough mail to get any data back from Google. However, the nice folks at SendGrid were kind enough to share their experiences with me and show me what the site looked like with real data, when I spoke at their recent customer meeting.
Who can register?
Anyone can register for Google Postmaster tools. All you need is the domain authenticated by DKIM (the d= value) or by SPF (the Return Path value).
Who can see data?
Google is only sharing data with trusted domains and only if a minimum volume is sent from those domains. They don’t describe what a trusted domain is, but I expect the criteria include a domain with some history (no brand new domains) and a reasonable track record (some or all of the mail is good).
For ESPs who want to monitor all the mail they send, every mail needs to be signed with a common d= domain. Individual customers that want their own d= can do so. These customers can register for their own access to just their mail.
ESPs that want to do this need to sign with the common key first, and then with the customer’s more selective key.
How does it work?
Google collects data from DKIM and/or SPF authenticated mail, aggregates it and presents it to a Google user that has authenticated the domain.
How do I authenticate?
