Validate/restrict email during registration for specific domain(s)

[Jer1479]

Is it possible to restrict registrations to only allow emails from a specific domain (or a list of domains)? Is this something that can be done with the ajax callback field in the registration fields setup? I know this can be done with other plugins or manually with very little regex code, but it’d be great to accomplish this with Userpro if possible.

Anyone have any recommendations? If this isn’t an option already, is it in the pipeline as a future feature?

Thanks!
