Add a way to manage/validate the email addresses of members allowed to join a team (BB-10238)
In the case where you may run a large team with contractors and other external entities, you may be interested to know which of those members do not have a primary contact email inside your company's domain. You may also wish to prevent users with unverified or non-domain email addresses from joining a team in the first place.
A possible way to do this would be to provide a filter up front that would only allow members with email domain xyz123.com to be added. And, for existing team members, the system could show somewhere which team members do not have a matching domain.
