An Introduction to Nodemailer Sendmail transport

Nodemailer is a well-known Node.js library. It allows us to easily send emails from our Node.js application. In fact, one of the transport methods for Nodemailer is the “sendmail”.

This option allows Nodemailer to rely on the local sendmail program to send emails. This comes in handy when we want to avoid an external email service, or if we want to use our own mail server. Furthermore, it is easy to use and does not need any additional setup.

In order to use the “sendmail” transport, all we have to do is install the Nodemailer library and then set the transport method to “sendmail”. For instance:

const nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
sendmail: true,
newline: ‘unix’,
path: ‘/usr/sbin/sendmail’
});

let mailOptions = {
from: ‘john@bobcares.com’,
to: ‘dave@bobcares.com’,
subject: ‘Subject of the email’,
text: ‘Text of the email’
};

transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log(‘Message sent: %s’, info.messageId);
});

Additionally, we have to ensure the path to the sendmail program is correct. We can find the path with the “which sendmail” command.

Additionally, the “sendmail” transport may not be available on all systems, so it’s recommended to use an alternative transport method, such as SMTP, if the “sendmail” transport is not available.

In conclusion, the “sendmail” transport in Nodemailer offers us an easy way to send emails using the local sendmail program. It’s a great option if you do not need to connect to an external email service and prefer to use our own mail server.
