+### Administrative SMTP test from Web — 2026-10-18
+
+The channel editor's **Send Test Email** action sends directly from Web through SMTP;
+it does not use the Worker or RabbitMQ. Its TCP 587 connection timed out while the
+production network policy allowed external SMTP only from Worker. The additive
+`web-to-external-smtp` policy in `production-network.yaml` grants Web the same public
+IPv4 TCP 587 egress as Worker, with the same private and cluster address exclusions.
+Apply this production overlay separately from the sandbox-only `notification.py`
+render. No SMTP credentials, channel settings, templates, or workload restart are
+required for this network change.

 The activation helper also persists the production user, queue and expanded Worker ACL
 in the `rabbit-definitions` Secret. The private password and matching RabbitMQ hash
 are saved with mode `0600`; updated `notification.py` reproduces that Secret during
