Explanation
Out of the five tasks, only verifying an email domain and adding a custom email address require org admin permissions. Configuring an email handler, customizing a notification scheme, and managing personal notification settings can be done by project admins or site admins.

Explanation
When you add a domain to user access settings, you can specify the default product role for each product in your organization. This determines the level of access that users with verified email addresses from that domain will have when they join your site. If you set the product role to None, users will not have access to that product unless you manually grant them access later.
