I had the same problem, and solved it via bring the from field into correspondence with the auth.user field.
i.e. something like the following will work for me.
var nodemailer = require('nodemailer');
let transporter = nodemailer.createTransport({
host: 'smtp.office365.com',
port: 587,
auth: {
user: 'test-user#gmail.com',
pass: 'password'
},
tls: { ciphers: 'SSLv3' }
});
let mailOptions = {
from: 'user-alias <test-user#gmail.com>', // sender address
to: 'myemail#companydomain.com', // list of receivers
subject: 'Hello ✔', // Subject line
text: 'Hello world ?', // plain text body
html: '<b>Hello world ?</b>' // html body
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message %s sent: %s', info.messageId, info.response);
);
Notice that the two occurence of test-user#gmail.com should be the same.
I think this is because some email server want to make sure that the declared email sender be same as the real email sender.
