nodemailer-relay v1.0.0

nodemailer-relay

Relay SMTP using nodemailer

About

This library adds a relay method to nodemailer to send email using the target domain's SMTP servers. It looks up MX records and attempts to send mail to each prioritized server until it either sends successfully, runs out of servers to try, or has a fatal send error on a valid server.

NOTE nodemailer is a peer dependency so that you can use the most up to date version which means it needs to be installed along with nodemailer-relay

Installation

npm install --save nodemailer nodemailer-relay

Example

import nodemailer from 'nodemailer-relay';

nodemailer.relay({
  from: 'foo@bar.com',
  to: 'baz@qux.com',
  cc: 'baz@bar.com',
  subject: 'Foo',
  text: 'Bar Baz Qux'
}, {
  'qux.com': {
    port: 587,
    secure: false,
    auth: {
      user: 'username',
      password: 'password'
    }
  }
})
.then(info => {
  console.log(info);
});
