Terminology

There is a lot more to say here, and I’m working on a longer post to really talk about the underlying racism in tech and how we as an industry have failed.

In the deliverability space, specifically, the use of blacklist/whitelist is terminology rooted in racism (black is bad, white is good). Many DNSBLs use the block terminology and have done for a while. But there are still too many places that talk about blacklists and whitelists (including here even though we make an effort to not use those terms).

Better terminology is blocklist and safelist. I recommit to using blocklist as the right terminology and commit to using safelist moving forward.

It’s not enough. It’s not the only thing I am doing to support equality and fight racism. But I’m making the commitment here, publicly.

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.

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.

Rethinking public blocklists

Recently, a significant majority of discussions of email delivery problems mention that neither the IPs or domains in use are on any of the public blocklists. I was thinking about this recently and realised that, sometime in the past, I stopped using blocklists as a source of useful information about reputation.

Five-Ten blacklist retired

The Five-Ten website has a notice that they have retired the blacklist. Five-Ten wasn’t the greatest list for blocking mail, they aggressively listed senders and there were a number of false positives against a standard mail stream. But it was useful as a touchpoint. If I had a client that wasn’t listed on Five-Ten that told me something about their normal practices.
