Error when trying to send email via SMTP with Directus and Docker

Question

I have Directus installed in a Docker Container running on a Linode instance. I am trying to send an email from the Directus instance using SMTP as the method but I am getting an error.

I am desperate for help with this error when trying to trigger this endpoint:

https://domain/directus/auth/password/request

Error:

POST /auth/password/request 204 102ms
WARN: [email] Error: write EPIPE
    err: {
      "type": "Error",
      "message": "write EPIPE",
      "stack":

    }

docker-compose.yml config for SMTP

EMAIL_SMTP_HOST: "hostname"
EMAIL_SMTP_PORT: "465"
EMAIL_SMTP_USER: "user@website"
EMAIL_SMTP_PASSWORD: "password"
EMAIL_SMTP_POOL: "true"
EMAIL_SMTP_SECURE: "true"
EMAIL_SMTP_IGNORE_TLS: "false"
EMAIL_SMTP_NAME: "hostname"

Does anyone know how to debug this issue?

Answer 1

I found the solution.

If you run into the same issue, here are the two Directus Config Options I had missed when trying to set up SMTP for Directus running on Docker.

EMAIL_TRANSPORT: "smtp"
EMAIL_FROM: "[email protected]

Add these to your docker-compose.yml file and your SMTP connection should work correctly.
