How to configure outbound email settings?
SMTP configure for Gmail

To configure outbound email, follow these steps:

    Open the console in your application
    Go to the folder /opt/bitnami/apps/edx/conf (Substitute /opt/bitnami for your installation directory for native installers)

    Add the credentials to the lms.auth.json and cms.auth.json:
        “EMAIL_HOST_USER”: “yourmailaccount@gmail.com”,
        “EMAIL_HOST_PASSWORD”: “password”,

    Finally restart the Apache server load the changes.

Pero mi servidor sendmail requería estos campos
EMAIL_PORT = 25
EMAIL_USE_TLS = False
EMAIL_HOST_USER = ”
EMAIL_HOST_PASSWORD = ”
