Make an is_admin? method on your user.
def is_admin?
  self.admin # Or how ever you figure out the person is an admin
end

In your validation:

validates_presence_of :email, :if => :is_admin?

That should do it.

By Ruby convention, the usual way of naming this method would be admin? 
-- and ActiveRecord already gives you that for free if you have an admin 
field.
