Mail now comes from no-reply@webhook.me.uk (DKIM, SPF and DMARC are
set up for it) and the Message-ID uses that domain instead of the
container hostname. The landing page gets a favicon, an Open Graph
image, canonical/OG/Twitter/JSON-LD tags, robots.txt that keeps
crawlers off email URLs, and a sitemap. Footer links to dixon.cx.
The landing page and the email shell drop the dark gradient look for a
white background, black text and a single Bristol blue accent. Copy is
unchanged. Email footers and docs now point at webhook.me.uk; the
dixon.cx hostnames keep working.
The PHP app, Apache, and .htaccess are replaced by a single Go binary
(standard library only). Routing, the JSON response, the landing page,
the shared email design, and all four parsers are ported with the same
output; JSON object keys are kept in sender order via an ordered decoder.
- mail.go: SMTP delivery with quoted-printable body and RFC 2047 subject
- main.go: routing, client IP from the proxy, /healthz, -check flag
- render.go: email shell, escaping, table helpers, generic renderer
- parser_*.go: github, grafana, json, wxinteract
- main_test.go: handler, response shape, IP forwarding, every parser
- Dockerfile: multi-stage build to distroless static, non-root, HEALTHCHECK
- deploy/webhooks.dixon.cx.service: systemd unit for the container
- README and PARSER_PROMPT updated for Go; IMPLEMENTATION_SUMMARY removed
The guide lived one directory above the repo, so the README links were
broken on GitHub. It also described the old layout: parsers inside
index.php, a copied <style> block, and div-based tables. It now covers
parsers/{name}.php, emailShell(), esc(), real table markup,
case-insensitive headers, and local testing with a sendmail override.
