-The key server uses [nodemailer](https://nodemailer.com) to send out emails upon public key upload to verify email address ownership. To test this feature locally, open the `credentials.json` file and change the `smtp.user` and `smtp.pass` attributes to your Gmail test account. Make sure that `smtp.user` and `sender.email` match. Otherwise the Gmail SMTP server will block any emails you try to send. Also, make sure to enable `Allow less secure apps` in the [Gmail security settings](https://myaccount.google.com/security#connectedapps). You can read more on this in the [Nodemailer documentation](https://nodemailer.com/using-gmail/).
