XF 1.4 Restrict email domain acceptable for signup?

[ColabRating]

I'm making a forum for cross-department collaboration at my University. I want to restrict who can sign up. Can I restrict users to signing up only with email addresses that end @(uni).ac.uk - either as standard or via a plugin?

There is no email white list built in, you'd need an add-on. Not sure if one exists.
