* Best practice, don't relay information about internal network structure to
the public, so no internal trace header
* you can only "trust" headers that are signed and pass validation
* totally legit to generate mails on the outbound server

Subject: [mailop] *Grumble* When is Amazon AWS going to properly inject trace
headers..
Just a rant..
Really hard to differentiate the good/bad/ugly ..
I am pretty sure the message is not generated on the outbound relay..
I don't really care HOW the record it, but as long as they record it..
Traffic leaving AWS..
(a14-188.smtp-out.amazonses.com)
Not a single received/trace header to be seen..
