Systems and methods for processing messages within a wireless communications system are disclosed. At least part of an encrypted message is received at a device for which it is intended. A security indicator on the device indicates that a message is encrypted. The message is decrypted, and it is determined whether the decrypted message includes a logical attachment. If there is such a logical attachment, an attachment indicator on the device indicates that the encrypted message includes an attachment associated with the message independent of the encryption attachment itself. The indicators may be updated via direct user action, or transparently and free from direct user input to said device.
