So.... Suppose I configure my email to send a "Thanks, we have received your email, we will reply shortly in office hours.". Whats the Holy Headers so even poorly configured servers don't cause a AutoReply Storm? Googling, I found "Precedence", "X-Auto-Response-Suppress",..? For something like this, normally I would scan lots of opensource projects in www.google.com/codesearch (so I can learn from the projects with a large number of hours in production) , but seems down at the moment.
