Nodemailer Error, 553 Relaying disallowed

Question

I am new to Nodemailer and I am getting this error when a user contacts me in a contact form. I am using express for this. Here is the error:

Error: Message failed: 553 Relaying disallowed as email@gmail.com

  responseCode: 553,
  command: 'DATA'
}

email@gmail.com is the email of the user trying to contact me, such as JohnDoe@gmail.com, etc. I am also using Zoho.

Here is my code:

var transport = {
  host: "smtp.zoho.eu",
  port: 465,
  secure: true,
  auth: {
    user: creds.USER, // I have a separate file with my email and password
    pass: creds.PASS, // I have a separate file with my email and password
  },
};
var transporter = nodemailer.createTransport(transport);
router.post("/send", (req, res, next) => {
  const { error } = contactValidation(req.body); // Just a separate function to validate If the user has submitted all entries using Joi
  if (error) return res.send(error.details[0].message);

  var name = req.body.name;
  var email = req.body.emailc;
  var message = req.body.message;
  var content = `name: ${name} 
 email: ${email} 
 message: ${message} `;

  var mail = {
    from: email,
    to: "myEmail@email.com",
    subject: "New Message from Contact Form",
    text: content,
  };

  transporter.sendMail(mail, (err, data) => {
    if (err) 
      console.log(err);
      res.json({
        status: "fail",
      });
    } else {
      res.json({
        status: "success",
      });
      transporter.sendMail(
        {
          from: "myEmail@email.com",
          to: email,
          subject: "Submission was successful",
          text:
            "Thank you for contacting us! We appreciate your feedback and will strive to get better!",
        },
        function (error, info) {
          if (error) {
            console.error(error);
          } else {
            console.log("Message sent: " + info.response);
          }
        }
      );
    }
  });
});

I have no idea what is the cause for this error.

I have tried:

Updating my Zoho DNS records using Zeit(now Vercel, I am using this for hosting my website)
Adding DKIM records to my email

I also do not know what this error means. If anyone can help, I would appreciate it! Thanks in advance.
