My experience shows that when things go wrong there is usually an amplified
feedback loop between your mail server and the remote, so ensure that any
header you set is one that you drop too.

This is also why the mighty no-reply@ was thought up, which simply drops
all mail. It might be crude, but it's effective.

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.



Any device or process that uses information from the infinitely forgeable
email headers is a process or device that can be subverted.
