We have a website that we wish to limit access to industry professionals (i.e. LinkedIn, Gmail and corporate email). We would like to prevent access to users who only have a personal or social email domain (i.e. Yahoo, Hotmail, AOL, MSN). Whitelisting does not seem an appropriate solution. Is there a mechanism for excluding non-professional email domains?

What do you consider a corporate email domain? You will need to do this in a pre-reg Action, and base it off of either a list or some similar characteristic of the emails.
