Nodemailer Email Delivery Issue on Live Server

Dear Zoho Support,

I'm encountering an issue with Nodemailer on my live server. While email delivery works flawlessly on my(localhost), it fails to send emails once deployed.

const nodemailer = require("nodemailer");

router.post("/register", (req, res) => {

const { fname, lname, email, subject, msg } = req.body;

try {

let transporter = nodemailer.createTransport({

host: "smtppro.zoho.in",

port: 465,

secure: true,

auth: {

user: "info@mydomain.com", //

pass: "myAppPassword", // },

});

const mailOptions = {

from: "info@mydomain.com",

cc: "info@mydomain.com",

to: email,

subject: "Website Form",

html: `

First Name : ${fname} <br>

Last Name : ${lname} <br>

Email : ${email} <br>

Subject : ${subject} <br>

Message : ${msg}

};

router.js existing idvisahub.com

transporter.sendMail(mailOptions, (error, info) => {

if (error) {

console.log("Error", error);

res.status(401).json({ status: 401, error });

} else {

console.log("Email sent" + info.response);

res.status(201).json({ status: 201, info });

}

});

} catch (error) {

res.status(401).json({ status: 401, error });

}

});

Troubleshooting Steps Taken:

I've verified the email address and password used in the auth section of the transporter configuration match my Zoho account credentials.

Double-checked all firewall settings on the server to ensure they don't block outgoing traffic on port 465.

Tested the email sending functionality on the server using a tool like telnet and was able to connect to Zoho's SMTP server.
