The relay stages each message in /tmp before pushing. readOnlyRootFilesystem left it with a read-only /tmp, so it answered '250 queued' and then dropped the message: no Gotify push, no error line. Mount an emptyDir at /tmp.

# SMTP -> Gotify relay for ZITADEL notifications.
|
|
#
|
|
# ZITADEL sends verification codes, password resets and one-time passwords by
|
|
# SMTP only, and this cluster has no working mail path: no SMTP credentials are
|
|
# configured for ZITADEL, and the notification table shows
|
|
# verified_email empty for every user. Without a delivery path nobody can finish
|
|
# a first login, at ZITADEL or at any relying party such as Forgejo.
|
|
#
|
|
# This relay accepts plain SMTP on :2525 and forwards every message to Gotify,
|
|
# so codes arrive on the phone through the existing gotify/igotify setup instead
|
|
# of email. ZITADEL then points DefaultInstance.SMTPConfiguration at this
|
|
# Service (see k8s/infra/iam/zitadel-values.yaml).
|
|
#
|
|
# The Gotify token is a Secret, never a literal here.
