Possible delivery states.

• DELIVRD
  The message has been delivered to the destination.
• EXPIRED
  The message has failed to be delivered within its validity period and/or retry period.
• DELETED
  The message has been cancelled or deleted from the MC.
• UNDELIV
  The message has encountered a delivery error and is deemed permanently undeliverable. Certain network or MC internal errors result in the permanent non-delivery of a message.
• ACCEPTD
  This state is used to depict intervention on the MC side. Sometimes a malformed message can cause a mobile to power-off or experience problems. The result is that all messages to that mobile may remain queued until the problem message is removed or expires. In certain circumstances, a mobile network support service or administrator may manually accept a message to prevent further deliveries and allow other queued messages to be delivered.
• UNKNOWN
  The message state is unknown. This may be due to some internal message centre problem which may be intermediate or a permanent. An MC experiencing difficulties that prevents it from returning a message state would use this state.
• REJECTD
  The message has been rejected by a delivery interface. The reasons for this rejection are vendor and network specific.
