I accept mail from the wild and reject bad SPF or bad DKIM.

It seems like something happened around 2026-05-01 (https://bigasterisk.com/post/delivered-email-rate-2026.png) where it became easier for spammers to make technically legitimately deliverable mails. Or my postfix is setup wrong.

Note "spf=pass" and "dkim=pass" in these headers:

  Return-Path: <[e-mail]>
  X-Original-To: [e-mail]
  Delivered-To: [e-mail]
  Authentication-Results: prime; spf=pass (sender SPF authorized)
