Hi guys, I’ve been trying to configure the user sign up email confirmation with the sender being our business Gmail address. However, I kept getting the 533 5.7.8 error. I’ve tried turning on the Less Secure App option too but it didn’t work neither. Any idea how to fix it?
Sorry, but unfortunately backendless can not help you. We just forward you the error from google. Double-check that the security in your google account are correct and your permissions are correct.
