responseCode: 535,
command: 'AUTH LOGIN'

in my simple NodeApp. i created .env file and put following values :

• EMAILJS_USER_ID=/* my EmailJS public key
• EMAILJS_SERVICE_ID=/* Service ID from EmailJS portal */
• EMAILJS_TEMPLATE_ID=/* Template ID from EmailJS portal */
• EMAILJS_PASSWORD=/*password */

and in my server.js file i have following code :

const express = require("express");
const bodyParser = require("body-parser");
const nodemailer = require("nodemailer");
require("dotenv").config();

const app = express();
const port = process.env.PORT || 3000;

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static("public"));

app.post("/send-email", (req, res) => {
const { email, comments } = req.body;

// Log request body for debugging
console.log("Request Body:", req.body);

// Configure nodemailer

const transporter = nodemailer.createTransport({
host: "smtp.office365.com", // Outlook SMTP server
port: 587, // Port for TLS
secure: false, // Use SSL/TLS when true for port 465, false for port 587
auth: {
user: process.env.EMAILJS_USER_ID, // Your Outlook email address
pass: process.env.EMAILJS_PASSWORD, // Your Outlook email password or app-specific password
},
});

const mailOptions = {
from: process.env.EMAILJS_USER_ID,
to: email,
subject: "Feedback Received",
text: comments,
};

transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.error("Error sending email:", error);
return res.status(500).send({ message: "Error sending email", error });
}
res.send({ message: "Email sent successfully", info });
});
});

app.listen(port, () => {
console.log(Server is running on port ${port});
});

You are not using EmailJS, so I am unsure what your question is.

i am using EmailJS, when i did client side implementation, it was going thru but credentials were exposed so i made my code NodeJS and used Node mailer and shifted the code. Once i did that this error start happening. Do you need any further details?

You use the nodemailer but want us to help you find your issues in the code. Is it correct?
Please go to the nodemailer developer and ask him. Or use the EmailJS service.
