Disable outbound email
You can configure Astro Private Cloud (APC) to not send outbound email.
Setting 
astronomer.houston.config.publicSignups: true with astronomer.houston.config.email.enabled: false is only secure when all non-OIDC authentication backends are explicitly disabled and the OIDC provider provides sufficient user validation to prevent untrusted users from accessing APC.To disable email transmission and email verification of users attempting to access the platform:
- In your 
values.yamlfile, setastronomer.houston.config.email.enabledtofalse. - Set 
astronomer.houston.config.publicSignupstotrue. - Remove the 
EMAIL__SMTP_URLlist-item fromastronomer.houston.secret.
