Email domain for organizations

[jace]

Organizations can have an optional but unique email domain. If specified, any user who has an email address with the same domain is automatically added to the Members group (see #28).

The user who is configuring the organization can only claim email domains that they have a currently valid email address at.

Known webmail domains can be blacklisted from the app's configuration.

Is this a stale issue, i.e. already resolved?

[jace]

No, it's still unimplemented. We haven't resolved whether email domains should be for organizations or teams.
