I want to create a mail delivery for notification in Graylog 6.2.2. I’ve tried using the docker-compose file and directly in the container, but unfortunately, neither of these methods worked, so the mail configuration appears on the interface.
GRAYLOG_SMTP_SERVER: "smtp.ionos.de"
GRAYLOG_SMTP_PORT: "587"
GRAYLOG_SMTP_USER: "${GRAYLOG_SMTP_USER:?Please configure GRAYLOG_SMTP_USER in the .env file}"
GRAYLOG_SMTP_PASSWORD: "${GRAYLOG_SMTP_PASSWORD:?Please configure GRAYLOG_SMTP_PASSWORD in the .env file}"
