The security classification metadata is extracted (716) on the mobile device from the email messages. A presentation characteristic for the email message is determined (718) based on a comparison of the extracted security classification metadata of the email message to a security classification policy. The email messages on the device can then be presented in accordance with the determined presentation characteristic of each respective email associated with the security classification metadata. In addition, in replying to an email in one or more subsets of recipients of the email message can be determined (908) where each of the recipients of a respective subset having at least one security classification in common. A visual indication (910) of at least one of the determined one or more subsets of recipients can be presented wherein the user can select (912) the reply group to ensure that only the appropriate recipients receive the email message. 130 Schema Acces I/ I| / 132 Pcy Control | 102 L - - - - - - - -- -/ 108 Network(s) - - 122 CP Nsorg Email Display 124 110 CpU Storage m Pah ~ 2 110Memory 120 112 a 1/0 Email Creation 126 Sensors R dio 1 - - - - - - - - Figure 1
