# The contact mailer — where its source is, and what it sends (2026-10-08)

Read-only. Method: the manifest, a search for the source, and strings of the binary copied out of the running pod (`kubectl exec … cat /app/contact-mailer`, no change to the pod).

## Manifest
```
5:#   1. Build and push the container image:
53:          image: contact-mailer:latest
55:          imagePullPolicy: Never
66:            - name: FROM_EMAIL
67:              value: "Felhom.eu <noreply@felhom.eu>"
68:            - name: TO_EMAIL
69:              value: "info@felhom.eu"
70:            - name: ALLOWED_ORIGIN
71:              value: "https://felhom.eu"
73:              value: "Europe/Budapest"
76:              value: "false"
```
## Source search (all empty except the manifest)
```
$ git -C felhom.eu log --all --name-only --format= | grep -i -E "mailer|contact" | sort -u
manifests/contact-mailer.yaml
$ find /mnt/5_hdd/felhom.eu ~ -maxdepth 5 -iname '*contact-mailer*'
/mnt/5_hdd/felhom.eu/git/felhom.eu/manifests/contact-mailer.yaml
```

```

**Reading:** one `sendViaResend` per form, to `TO_EMAIL` (info@felhom.eu), with `reply_to` set to the visitor; no second send (no confirmation to the visitor). The operator's notification HTML is Hungarian. The page shows its own status messages, not the server's (`kapcsolat.html` / `en/contact.html` `showStatus`), so the English page needs no mailer change. Gap: R-902.
