CUNY Academic Commons

See https://redmine.gc.cuny.edu/issues/9979#note-7 and follow-up comments.

@login.cuny.edu email addresses appear to be used for logging into CUNYFirst and other CUNY-wide services, but they do NOT appear to be linked to real inboxes. This means that they should not be used for Commons registration, since user accounts need real email addresses. Otherwise, they can't be activated.

So, two tasks:

1. We should confirm that the above is correct. Of the 117 Commons registrations using login.cuny.edu, 16 of them have been activated at some point. This means that there must be something more complicated going on. Maybe @login.cuny.edu forwards to a campus email in some cases? (Didn't work for me, but it's a complicated system.) Or maybe these 16 were manually confirmed?

2. If it's true that there's no inbox, we should have some logic during registration that detects login.cuny.edu addresses being entered, and lets users know that it's not valid for registration. I guess this could take the form of a client-side check that will add a little notice under the email box with an error message (text tbd). We could then prevent the form from being submitted.
