Never seen. Messages sent from EOP are routed directly, need to pass on-prem (centralized mail transport) or go through some SaaS mail hygiene appliance/service? Sure there is no address rewriting taking place somewhere? Take an OOF, locate its Message ID and make a message trace with details to see how it was sent and processed.
