Event ID: 3015 Source: MSExchangeTransport

A non-delivery report with a status code of 5.3.0 was generated for recipient <recipient> (Message-ID <ID>).
Causes: Exchange mistakenly attempted mail delivery to an incorrect MTA route.  
Solution: Check your route and topology; use the winroute tool to ensure the routes are properly replicated between servers and routing groups.
As per Microsoft: "If the MTA Stacks service has been disabled and stopped for a long time, and then is re-enabled and started, the SMTP Store Driver may determine that the MTA is not started and return an NDR for messages bound for valid MTA recipients". See MSEX2KDB for additional information on this event.
