We strongly recommend using a dedicated email service. Email server setup and maintenance is _very_ difficult even for experienced system administrators, and getting any part of the complex required email setup wrong means your email won't be delivered, or worse, delivered erratically.
**Please note that in any email provider, you _must_ verify and use the subdomain, e.g. `discourse.example.com`. If you verify the domain only, e.g. `example.com`, mail will not be configured correctly.**
Enter these values when prompted by `./discourse-setup` per the [install guide](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md#edit-discourse-configuration):
