Sending emails from OCI with Email Delivery service in node.js


Oracle Cloud Infrastructure Email Delivery is an email sending 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.

Go to a IAM/user and click on [Generate SMTP Credentials] as shown below:

Keep the credentials created in a safe place:

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

Grab the connection details:

Now test the code:
npm install nodemailer

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 opc@10.0.2.94</b>", 
    });
    console.log("Message sent: %s", info.messageId);
    console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));
  }
  main().catch(console.error);

Test it:

node sendmail.js

That’s all, hope it helps! 🙂

    Gives 535 error when secure is false. When secure is true, there is an error with sslv3, which also added via ttl option in nodemailer transporter.
