When a site is configured to only allow login from email addresses with a particular domain, the sign up screen done properly prevent creating accounts with an email address from another domain.

See the current flow here.

```
1. Site setting is configured to only allow email from your domain:

```
2. User tries to sign up with a different domain, form says email is valid:

```
3. User is told email from that domain not allowed after clicking Create Account

It’d be a better user experience if the client-side validation showed the problem in step 1, before the Create Account button is clicked.
