Problem

• Someone connecting an app over SMTP needs the host, ports, a key and a way to check it works, and today they would have to read several pages to get them.
• Top layer of the stack, on feat(workflows): add the smtp relay #130795. Resend's setup page shows copyable settings only.

Changes

• A new SMTP tab in Transactional, behind workflows-smtp-relay, shows the host, ports and username to copy.
• Create a key makes a key that can only send, and shows it once.
• Send test email connects to the relay as an app would, and shows its reply as is, such as 535 for a bad key.
• Recent problems lists refused mail and dropped headers from the last 7 days. Resend has no equivalent.
• Copyable settings for Nodemailer, Django and Laravel.
• New docs page, with reply codes, at docs/published/docs/workflows/smtp.mdx. A person asked for it in the request for this work.
• SMTP_RELAY_HOST empty shows that this instance has no relay.
• Send test email refuses a From with line breaks and a key PostHog can't send over SMTP, with a clear error.

How did you test this code?

Driven in a browser on the local stack, with real SMTP behind the button:

• Created a key, then created a second one. The first version failed the second time because labels must be unique, and the label now carries the time.
• Sent a test with a bad key (535), to an address with no mail server (550), and from a verified domain to the SES simulator. The row appeared in the log and in email_status_events.
• Rendered at 900 px wide.
• Clicked Send test email again with one wrong key until it showed 454 Too many failed logins, then with a working key from the same place: queued. Typed a non-ASCII key: an error toast, and no 5xx in the network log.
• The page has no way to type a line break in From, so that case was an API call from the logged-in browser: 400, attr: from.
• Not tested: dark mode, or a project with no sender (banner only seen in code). Copy buttons were not clicked. The setup page was not run against a real public host name.

Test rationale: test_smtp_relay.py catches a setup page shown with the flag off, a test send that hides the relay's reply, and input that would fail with a 500. Story added with no snapshot.

Release status

• This change is behind a feature flag and is not available to users

Docs update

New page in this PR. The sending-transactional-emails skill gets a short section.

More context for AI agents

• Decisions: Test goes over real SMTP from Django, so it catches a bad key, a blocked port or an expired certificate. The key is used once and not stored.
• Follow-ups: Quill version for today-rail-nav.
• Read closely: send_smtp_test in services/smtp_relay.py. Django needs network access to the relay host.

⚠️ Trunk lane — backend Python lane, mixes lanes

This PR is assigned to the backend Python lane. It runs backend Python tests and may merge in parallel with PRs in other lanes.

This PR changes Python or frontend code (frontend/src/lib/constants.tsx, frontend/src/products.tsx, posthog/jwt.py and 25 more) and Node or Rust code (nodejs/package.json, nodejs/src/capabilities.ts, nodejs/src/cdp/cdp-api.serial.test.ts and 25 more) together. In the merge queue, every Node or Rust PR behind it in the same lane then runs the Django and frontend suites too, so the cross-lane check fails. Split it, or add the cross-lane-change label if the halves must land together.

⚠️ Complexity (TypeScript) — 3 functions above the limit (max 14)

Cyclomatic complexity above the limit in changed typescript files (10 for production files, 15 for test files). Warn only: worth simplifying when you next touch these functions.

✅ Frontend layers — no new upward imports, 0 removed

Static imports from a lower frontend layer into a higher one (layers, lowest first: kernel, shell, query, features). Compared with the base branch, so an import that a PR also adds to layer-baseline.txt still shows here. Sizes are the source bytes on the eager path of every logged-in page.

Layer	Eager source bytes	Δ vs base
kernel	2.97 MiB	🔺 +778 B (+0.0%)
shell	2.36 MiB	🔺 +123 B (+0.0%)
query	56.2 KiB	no change
features	273.8 KiB	no change

✅ Toolbar bundle — eager 2.42 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Metric	Size	Δ vs base	Budget
Eager (shipped) entry + static imports	2.42 MiB · 19 files	🔺 +1.3 KiB (+0.1%)	████░░░░░░ 42.3% of 5.72 MiB
Deferred (lazy)	2.62 MiB · 42 files	🔺 +987 B (+0.0%)	n/a — loads on demand
