Redmine

When a Redmine instance is accessible via the Internet, it would be helpful if Administrators can pre-define a set of domain names that allow users with email address at those domains to self-register.

For example, if the Redmine instance is run by company "My Compamy", then the only users that can self register are the ones with @mycompany.com, @mycompany.net, etc. email addresses.

Thanks.
