Manage Teams Email Integration via powershell

Question

Hello,

Would like to enable Email integration in Teams. As per Microsoft Article "To turn on email integration, make sure that Allow users to send emails to a channel email address is On. Next, check to make sure that the domain for the sender's email address isn't blocked in Teams Admin Center>Org-Wide settings>Teams Settings>Email integration>Accept channel email from these SMTP domains. It should be either blank or includes all the domains that you expect to receive emails from"

Does that mean if I want to restrict email to teams channel only via Internal users (all domains in a tenant) all AAD domain should be added in the list?

Thanks
