How do I set up outbound SMTP using Courier?
How do I use outMail with Courier?


In this article we discuss using outMail as the outbound email server for Courier.  Courier is a Multi-Channel Notification API Platform.  We assume already you have a working Courier set up and you are looking at configuring the SMTP Server settings to use outMail.

More detailed information can be found in their online documentation - Courier uses the Nodemailer for its SMTP transport so to configure Courier to use outMail for its outbound SMTP you will need to edit/create a file called override.smtp.config with the following data:

  "event": "outMailSMTPExample",
  "recipient": "Fred Test",
  "profile": {
    "email": ""
  "override": {
    "smtp": {
      "config": {
        auth: {
          user: "outmail-username",
          pass: "outmail-password"
        host: "",
        secure: true,
        port: 465
