This is a sweet one...
I selected "Server/Provide server feedback.." which opened and email prefilled with various details including the "to" email of "Server-Feedback@group.apple.com".
It also has instructions so that they can receive pertinent logs, diagnostics, etc.
Only problem is the provided email CANNOT be received from outside the apple network. The email will bounce back as undeliverable as per below extract
I'm confused ??
