Nodemailer - SMTP Timeout - office365
Question
I am trying to use SMTP connection with nodemailer with office365 mail.
When I try to send mail, it throws up this error -
Error: connect ETIMEDOUT xx.xxx.xxx.xxx:587 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1161:14) errno: 'ETIMEDOUT', code: 'ECONNECTION', syscall: 'connect', address: 'xx.xxx.xxx.xxx', port: 587
It is not a proxy issue, since I tried outside of the network and it throws up the same error as well.
`
var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
host: 'smtp.office365.com',
secure: false,
auth: {
user: "xxxxx@xxx.com",
pass: "xxxxx"
},
tls: {
ciphers: 'SSLv3'
}
});
var message = {
from: 'Sender Name <xxx@xxx.com>',
to: '"Receiver Name" <xxx@xxx.com>',
subject: 'Nodemailer',
text: 'Hello to myself!'
};
transporter.sendMail(message, function(error, response) {
if (error) {
console.log('Error occured');
res.end("<html><body><h1>error</h1></body></html>");
console.log(error);
return;
} else {
console.log(response);
res.end("<html><body><h1>success</h1></body></html>");
console.log('Message sent successfully!');
}
});
`
I tried with other services as well like Gmail, it also gives the same error inside and outside the network.

Do you have a local firewall or anti-virus product that does port blocking? My company routinely blocks computers from making outbound connections on common SMTP ports because it was a common multi-mailer virus propagation path. smtp.office365.com responds on both port 25 and 587 from a host I know to be able to initiate outbound SMTP traffic.
[~]# nmap -p25,587 smtp.office365.com
Starting Nmap 7.60 ( https://nmap.org ) at 2018-12-04 10:39 EST
Nmap scan report for smtp.office365.com (40.97.170.178)
Host is up (0.027s latency).
PORT STATE SERVICE
25/tcp open smtp
587/tcp open submission

this might be a bit late but this is more for anyone else in the future.
Common cause for timeouts is you have to enable SMTP, if using a mac this can be done through PowerShell then look to here . If youre on a mac, you'll have to install WSman because it doesnt come with powershell. run on port 587 . set secure to false . then make sure your config email and the email in your auth and data for postman are the same.
