I have a nodejs + express backend and I need to send an email to new subscribers containing a link to check if they actually own the address they submitted. At first I tried using sendmail because I didn't want to create a new email address and authenticate each time, but my emails kept getting rejected. Then I tried using nodemailer with a gmail account, but it looks like gmail doesn't like people authenticating from third party apps. Then I tried creating a zoho account (I read here on stackoverflow that it works fine and it would have been cool to have a personalized domain) but it required me to add a dns txt record to prove I "own" the domain (I'm hosting the website on render and I can't add dns records). Now I'm trying to use an aol address (it's one of the well known providers for nodemailer) but it won't let me authenticate, I tried authenticating both using the default port (587 in nodemailer) and the 465 port (got it from aol docs) but I got the same result. Here's the code I'm using:

const transporter = nodemailer.createTransport({
                            service: 'AOL', 
                            auth: {
                                user: process.env.MAIL_ADDR, 
                                pass: process.env.MAIL_PASS, 
                            },
                            port: 465
                        });

                        const mailOptions = {
                            from: process.env.MAIL_ADDR,
                            to: email,
                            subject: 'Codice di verifica dazeku',
                            text: "Verifica la tua email al link "+process.env.API_HOST+"/checkEmail?mctoken="+token
                        };

                        transporter.sendMail(mailOptions, (error, info) => {
                            if (error) {
                                console.log('Errore durante l\'invio dell\'email:', error);
                            } else {
                                console.log('Email inviata:', info.response);
                            }
                        });

And here's the error I'm getting:

I'm looking for ANY kind of solution, I just need it to be free.

  • Did you see the error message? "Too many bad attempts" --- maybe you need to wait (an hour? a day?) before you try again. Make sure your user name and password is correct. Did you [configure less secure](https://support.cdesoftware.com/kb/a1909/535-5_7_0-auth005-too-many-bad-auth-attempts-error-when-trying-to-send-email_.aspx) access? Gmail would require the same, btw. – Robert Aug 15 '23 at 21:44
  • Username and password are correct, it's been 16 hours now and I still can't access, then I've been getting that same error since the first time I tried so I doubt it's about the number of bad attempts. In the last couple of years both Gmail and AOL removed the possibility to configure less secure access. The only solution I can think of is generating an app key but on AOL the function is temporarily unavailable. – Vincenzo Pepe Aug 16 '23 at 13:13
