Restrict registration with github account by email domain

[KarthikeyanRaju-T2S]

Hi Team,

I am trying to restrict user registration by domain name, because the current implementation seems open for all, who ever having the domain name, they are able to register as user and use the service, so Is there a way to restrict the user registration by domain name ie: example.com.

So, if someone try to register with email info@example.com it should allow, if some one trying with the email persona@gmail.com it will be deny.

Can we have this kind of secured way for github OAuth?
