From 30b3b394a6fbc231e1ae638a355d4936fc808a60 Mon Sep 17 00:00:00 2001 From: Pieter Date: Tue, 13 Jan 2026 09:52:23 +0100 Subject: [PATCH] fix: Resolve Authentik email delivery issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixed email FROM address formatting that was breaking Django's email parser. The display name contained an '@' symbol which violated RFC 5322 format. Changes: - Fix Authentik email FROM address (remove @ from display name) - Add Mailgun SMTP credential cleanup on server destruction - Fix Mailgun delete task to use EU API endpoint - Add cleanup playbook for graceful resource removal This ensures: ✓ Recovery emails work immediately on new deployments ✓ SMTP credentials are automatically cleaned up when destroying servers ✓ Email configuration works correctly across all environments 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- ansible/playbooks/cleanup.yml | 40 +++++++ .../templates/docker-compose.authentik.yml.j2 | 29 +++-- ansible/roles/mailgun/tasks/delete.yml | 64 +++++++++++ ansible/roles/mailgun/tasks/main.yml | 103 ++++++++++++++++++ scripts/destroy-client.sh | 20 +++- 5 files changed, 244 insertions(+), 12 deletions(-) create mode 100644 ansible/playbooks/cleanup.yml create mode 100644 ansible/roles/mailgun/tasks/delete.yml create mode 100644 ansible/roles/mailgun/tasks/main.yml diff --git a/ansible/playbooks/cleanup.yml b/ansible/playbooks/cleanup.yml new file mode 100644 index 0000000..508d05a --- /dev/null +++ b/ansible/playbooks/cleanup.yml @@ -0,0 +1,40 @@ +--- +# Cleanup playbook -
