I am building a product that works automatically for all the people "inside" an e-mail domain. So everybody that's a part of @yesgraph.com would have access to all of the content from other people with the @yesgraph.com e-mail address.
It "feels stupid" because I don't want to allow any sort of generic domain and off the top of my head I can think of 20 generic e-mail domains, not event counting the ones I don't think of.
In the situation I need it in, that's an OK solution, but I was interested in finding out if there exists a better solution.
