Hi, I am setting up self-hosted signoz and have troubles with SMTP authentication. I managed to configure it through the helm chart like

queryService:
  additionalEnvs:
    SMTP_ENABLED: 'true'
    SMTP_FROM: <email>
    SMTP_HOST: <http://email-smtp.eu-central-1.amazonaws.com|email-smtp.eu-central-1.amazonaws.com>
    SMTP_PORT: '587'
    SMTP_AUTH_USERNAME: <AWS SES user>
    SMTP_AUTH_PASSWORD: <AWS SES password>

But when I invite a new user I get the following error message:

{
    "level": "ERROR",
    "timestamp": "2024-07-31T12:19:39.033Z",
    "caller": "auth/auth.go:134",
    "msg": "failed to send email",
    "error": "530 Authentication required",
}

with stacktrace:

Can someone help here? From what it looks like to me, the

smtp.PlainAuth

is missing.

@Florian Schröder, plain auth is not missing. The env should be

SMTP_USERNAME

and

SMTP_PASSWORD

for query-service . Where did you find the ref of

SMTP_AUTH_USERNAME/PASSWORD

Oh, I see. I basically copied from here: https://signoz.io/docs/operate/query-service/user-invitation-smtp/#kubernetes
