The ReceivedList Property syntax has these ReceivedList:
Part
Description
object
An expression
evaluating to an object of type Pop3Msg.
Remarks
ReceivedList property returns collection of all 'Received'
headers found in the message, parsed to one more more
Pop3Rec objects. Each Pop3Rec
object will try to provide information about hosts that exchanged
the message until it finally reached your inbox. Information
provided in Pop3Rec purely depends on data provided by those hosts -
there's no general rule what exactly will server provide.
