This seems a reasonable approach, given a configurable delivery delay 
tolerance. One could also cross-check References headers against messages 
already received, to set a lower limit on the time stamp. If a message 
claims to have been sent prior to one it references (modulo some 
tolerance), then it can be bounced/modified/moderated.
