Mail contains demo data related to private discussions. However this kind of
use of mail has been removed since several versions. This demo data only
creates noise in mail.message without adding any real demo for any users.
As messages should be linked to existing business documents, existing
demo data in demo channel and additional messages coming in other applications
should be sufficient. Let us remove those demo you can see only in technical
menus.
