From fec3826fd817c7e3af28570743951e11703c51e5 Mon Sep 17 00:00:00 2001 From: InferenceBot Date: Sun, 1 Nov 2026 21:58:41 +0000 Subject: [PATCH] migration plan: port 25 inbound confirmed open; outbound 25 not needed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Nathan confirmed in the Infomaniak portal that inbound 25 is open, which settles the half that matters most: receiving cannot be replaced by a relay, whereas sending can and will be. So the mail architecture is now: receive on the box, send through Scaleway Transactional Email. That makes an outbound-25 request unnecessary — the plan previously left both halves open, which would have cost a support ticket for nothing. Remaining ports listed as still to confirm rather than assumed. --- cloudron-server-migration.md | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/cloudron-server-migration.md b/cloudron-server-migration.md index ad72a87..d420f3c 100644 --- a/cloudron-server-migration.md +++ b/cloudron-server-migration.md @@ -85,7 +85,9 @@ needed to restore are inside the thing being restored.
