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

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: test#abc.com,
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?
{ Error: Invalid login: 530 Must issue a STARTTLS command first.

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
}
});

Answer 2

After going through the typings( "#types/nodemailer") file I added the following flags
1) service :'Zoho'
2) requireTLS :false
it is working now :)
let transporter = nodemailer.createTransport({
service:'Zoho',
host: this.service,
port:587,
secure: false,
ignoreTLS:true,
requireTLS:false,
auth: {
user: this.user,
pass: this.password
}
});

Answer 3

In the year 2022, I got this on the official documentation https://nodemailer.com/smtp/well-known/
let transporter = nodemailer.createTransport({
service: 'SendPulse', // no need to set host or port etc.
auth: {
user: 'account.email#example.com',
pass: 'smtp-password'
}
});
transporter.sendMail(...)
So, for Zoho just simply:
let transporter = nodemailer.createTransport({
service: 'Zoho', // no need to set host or port etc.
auth: {
user: 'account.email#example.com',
pass: 'smtp-password'
}
});
transporter.sendMail(...)
Just test it and works. I believe it doesn't need to put any setting if we use "Well-known services"
Hope this helps someone drop by in this thread :).
