Use this payload on an iOS device to specify which mail domains will be marked in Mail, and which web domains’ documents are considered managed.
Unmarked email domains
Mail messages are marked if they aren’t addressed to domains in the approved list. For example, a user could have both example.com and group.example.com in their list of known domains. If the user entered anyone@foo.com, that address would be marked so the user would clearly know the domain wasn’t in the list.
Managed Safari web domains
Downloads from Safari will be considered managed documents if they originate from a managed domain. For example, if a user downloads a PDF using Safari from a managed domain, that PDF complies with all managed document settings.
Important: You must disable “Allow documents from managed sources in unmanaged destinations” in the iOS restrictions settings payload in order for documents downloaded from Safari to be managed.
