Managed Domains
Use the Managed Domains profile configuration to configure managed domains for your devices. Setting up managed domains allows you to visually differentiate trustworthy email and web domains from unfamiliar or untrustworthy ones.
Emails that are received from domains that are specified in this configuration are highlighted blue, while any unspecified domains will be highlighted red.
When a web domain is specified, any files that are downloaded from that web domain will be opened in a specified application.
