Multisite: Check only valid looking emails against banned domain list. 

If an email address is missing an `@`, we can't assume enough to check it against a list of domain names.

Additional validation of email should happen in `is_email()` before being passed to `is_email_address_unsafe()`.

Fixes #39915.
