From 01585534f9375ddb45a068608faf08c8ae9977b0 Mon Sep 17 00:00:00 2001 From: CTO Agent Date: Sat, 1 Aug 2026 08:58:03 +0000 Subject: [PATCH] Remove HTTP listener IP restrictions from Stalwart config Issue: Stalwart was blocking Traefik ingress controller's IP (10.244.2.227) with "Blocked IP address" errors, causing 502 Bad Gateway responses. Root cause: The allowed-ips security restriction on the HTTP listener was blocking legitimate internal cluster traffic from Traefik. Fix: Remove the [server.listener.http.security] section entirely. The HTTP listener is already protected by: - Running as ClusterIP service (not exposed externally) - Traefik ingress with TLS termination - Kubernetes NetworkPolicies (when enabled) Internal cluster traffic should not be IP-restricted. Related to DEV-422 (Stalwart not accessible).
