Inside Email verification you can select 'Update your e-mail in project data', to change it to a catch-all email.
I'm not really clear on what this function does and second if this change only applies to that particular project or to all projects in which you use this (hotmail) address.
hotmail is no catchall email. Catch all is only supported if *@domain.com goes to one email address. OF course this is not the case with hotmail as it is not under your control.
The setting is for one project only.
