I have the following as my nodemailer script:
'use strict';
const nodemailer = require('nodemailer');
// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
host: 'localhost.com',
port: 465,
secure: true,
auth: {
user: 'user',
pass: 'pass',
}
});
module.exports = (msg) => {
let { from, to, subject, html } = msg;
// setup email data with unicode symbols
let mailOptions = {
from,
to,
subject, // plain text body
html,
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message %s sent: %s', info.messageId, info.response);
});
}
When I try to run the function I receive the following error:
{ Error: 139970611431232:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:../deps/openssl/openssl/ssl/s23_clnt.c:794:
code: 'ECONNECTION', command: 'CONN' }
I did have my config setup for postfix to use port 465 and 587 and still got the same response. Perhaps it's an issue with calling on localhost even though my postfix server is setup with the host being the domain to my website? I do have my postfix setup with ssl as well. Any ideas are welcome. Thanks in advance.
Update: I'm 90% sure this is an issue with the credentials I'm providing to nodemailer but I can't find out where the disconnect lies. The postfix server is working fine at sending messages on its own but not via a script. I've tried different ports and different config setups but I can't figure out what's going wrong and the error is not very helpful.

In the nodemailer script, I am passing in my username and password of the account on my server that is receiving the mail. I can send and receive mail just fine via the command line but I have not had any successfully sent through this script. Thanks a lot for any help. I'm running Ubuntu 16.04. I have tried allowing the port numbers via ufw.

Update: Still having this issue... can't figure out what is wrong in my postfix setup that is allowing emails to be sent via the terminal but not via nodemailer.
