Configure SMTP for outbound emails

Google Cloud Platform doesn’t allow SMTP traffic through default ports: 25, 465, 587. Check Google cloud documentation to learn how to use a VPN to bypass these restrictions or use a different port for sending emails from your application.

Configure the email settings in the /opt/bitnami/apps/ghost/htdocs/config.production.json file by adding the code below just after the database section. Here’s an example using Gmail. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.

mail: {
    from: '',
    transport: 'SMTP',
    host: '',
    options: {
        service: 'Gmail',
        port: 465,
    secure: true, // use SSL
        auth: {
            user: '',
            pass: 'PASSWORD'

Then, restart all services for changes to take effect:

$ sudo /opt/bitnami/ restart ghost
$ sudo /opt/bitnami/ restart apache

To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid or Mandrill, refer to the FAQ.

NOTE: If you are using Gmail as the outbound email server and have experienced issues trying to send emails correctly, check the Gmail SMTP troubleshooting page to learn the causes of these issues and how to solve them.
