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.

For the system to be able to send emails, set the mail server to use and the host name of your Re:dash server. Do this by adding the lines below in the /opt/bitnami/apps/redash/htdocs/.env file.

The example shown below uses Gmail for outbound email. Remember to update this with equivalent values for your SMTP host or, if using Gmail, replace the USERNAME and PASSWORD placeholders with correct values for your Gmail account.

export REDASH_MAIL_SERVER="" # default: localhost
export REDASH_MAIL_PORT="587" # default: 25
export REDASH_MAIL_USE_TLS="true" # default: False
export REDASH_MAIL_USE_SSL="true" # default: False
export REDASH_MAIL_USERNAME="" # default: None
export REDASH_MAIL_PASSWORD="PASSWORD" # default: None
export REDASH_MAIL_DEFAULT_SENDER="" # Email address to send from
export REDASH_HOST="" # base address of your re:dash instance, for example: ""

After making the changes, restart all servers:

$ sudo /opt/bitnami/ restart

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