Oracle Cloud Infrastructure (OCI) Email Delivery is an email notification service that provides a fast and reliable managed solution for sending high-volume emails that need to reach your recipients’ inbox. Email Delivery provides the tools necessary to send application-generated email for mission-critical communications such as receipts, fraud detection alerts, multi-factor identity verification, and password resets.

In this tutorial, we'll cover all the basics to get you up and running with the Email Delivery service!

Set up Email Delivery

  1. Go to IAM/user and select Generate SMTP Credentials as shown below:

    {% imgx assets/ociemailimage-6.jpg %}

  2. Keep the credentials created in a safe place:

    {% imgx assets/ociemailimage-7.jpg %}

  3. Create an Approved Sender (a real, existing email account to put in the from field):

    {% imgx assets/ociemailimage-8.jpg %}

  4. Grab the connection details:

    {% imgx assets/ociemailimage-9.jpg %}

  5. Now, test the code:

    npm install [nodemailer](https://nodemailer.com/about/)

  6. Create a sendmail.js file:

    var nodemailer = require('nodemailer');
async function main() {
let testAccount = await nodemailer.createTestAccount();
let transporter = nodemailer.createTransport({
  host: "smtp.email.eu-frankfurt-1.oci.oraclecloud.com",
  port: 25,
  secure: false,
  auth: {
    user: 'ocid1.user.oc1..aaaaaa...om', 
    pass: 'BD..._', 
  },
});
let info = await transporter.sendMail({
  from: '"javier...om', 
  to: "javi...om", 
  subject: "ssh access to 10.0.2.94",
  html: "<b>ssh -i deltakey -o ProxyCommand=\"ssh -i deltakey -W %h:%p -p 22 ocid1.bast...oud.com\" -p 22 [email protected]</b>", 
});
console.log("Message sent: %s", info.messageId);
console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));
}
main().catch(console.error);

Test the configuration

Now that you have Email Delivery set up, let's verify that everything is working properly. In a console window, run:

node sendmail.js

{% imgx assets/ociemailimage-10.jpg %} {% imgx assets/ociemailimage-11.jpg %}

And that's it! If your local output is similar to what's shown above, you're all set and ready to receive notification emails!
