Tangential, will email host spam reputation rely on IPv4 scarcity forever?
- dspillett 2y agoFor longer, I expect. For a long time email has been partially centralised so for most real people and a lot of systems mail goes out through a specific host (or small number of hosts) on the edge of their network or completely outside it (sending individuals sending via services like gmail, and systems using services like sendgrid, and so forth) so the need to push for IPv6 is less apparent for mail sending than a number of other things. There are orders of magnitude less hosts sending mail than, say, making HTTP(S) requests.
