Answer 1

ask them to get a web based e-mail- that's about all you can do

No generic addresses: Email addresses such as [e-mail] or [e-mail] cannot be used to join a group. Messages from Groups should be personal and should not use email addresses which commonly recycled within an organization. In addition, spammers commonly target these addresses. For all these reasons, we disallow their user on the service.
