The Exchange Team has given a bit of thought to the message headers in Exchange 2013.
This is a direct result of the number of transport services in 2013. The “new” message headers make it easier to figure out which transport service dealt with the email at a given time. This is quite handy as there are three transport services in a mailbox role and one in CAS.
The header exposes the version of Exchange as well – 15.0.712.22 in my case (CU2).

Keep an eye on the transport service in the message headers and you will be able to troubleshoot problems quicker ;)
