From 7716e7e26ec833aed3bd953dbc64a3635de4b1f2 Mon Sep 17 00:00:00 2001 From: Philip Peterson <1326208+philip-peterson@users.noreply.github.com> Date: Fri, 5 Jun 2026 00:39:28 -0700 Subject: [PATCH] Switch to postmark+smtp transport to avoid header restrictions Postmark's API transport rejects headers like Return-Path that Drupal adds automatically. The SMTP relay is more permissive and avoids this class of rejection entirely.
