nodemailer and zoho email issue '530 Must issue a STARTTLS command first.'

Question

I am using the latest version of nodemailer version 4.1.0. I tried using the sample code available here https://nodemailer.com/smtp/

Here is my code

 let transporter = nodemailer.createTransport({
        host: 'smtp.zoho.com',
        port:587,
        secure: false,           
        auth: {
            user: this.user,
            pass: this.password
        }
    });

     var mailOptions: nodemailer.SendMailOptions = {
        from: ****@***.com,
        to: [email protected],
        subject: 'Hello ✔',
        text: 'Hello world ✔', 
        html: '<b>Hello world ✔</b>'
    };

   transporter
            .sendMail(mailOptions)
            .then(
                (info) => {
                  //  console.log(info);
                    resolve({status: info.messageId})
                }
            )
            .catch(err => {
             //   console.log(err);
                reject({status: err.toString()})
            })

I get the following error. I have set the secure flag as false, and have also used ignodeTLS. The previous version of nodemailer 0.7.1 did not have any issues. Am I missing out on any specific configuration?

Answer 1

you can also use this without these tls parameter default value is false. you got the error because of you don't pass service:'zoho' in nodemailer

let transporter = nodemailer.createTransport({
        service:'Zoho',
        host: this.service,
        port:587,
        secure: false,
        auth: {
            user: this.user,
            pass: this.password
        }
    });
