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.
If that's what you want to do, then setting one or more of these may help: Auto-submitted: auto-generated X-Auto-Response-Suppress: OOF Precendence: bulk (Other values of the last two are possible). RFC3834 is background reading and references Auto-submitted:. X-Auto-Response-Suppress: is used by MS Exchange/Outlook. But if those servers really are "poorly configured", there's no guarantee they will honour any of those anyway. If you want more control for yourself, you need to filter the return messages out. I do this in Exim to identify "automatically generated email" to be thrown away in some circumstances: condition = ${if or { \ { match {$h_precedence:} {(?i)junk|bulk|list} } \ { eq {$sender_address} {} } \ { def:header_X-Cron-Env: } \ { def:header_Auto-Submitted: } \ { def:header_List-Id: } \ { def:header_List-Help: } \ { def:header_List-Unsubscribe: } \ { def:header_List-Subscribe: } \ { def:header_List-Owner: } \ { def:header_List-Post: } \ { def:header_List-Archive: } \ { def:header_Autorespond: } \ { def:header_X-Autoresponse: } \ { def:header_X-Autoreply-From: } \ { def:header_X-eBay-MailTracker: } \ { def:header_X-MaxCode-Template: } \ { match {$h_X-Auto-Response-Suppress: } {OOF} } \ { match {$h_X-OS:} {HP Onboard Administrator} } \ { match {$h_X-MimeOLE:} {\N^Produced By phpBB2$\N} } \ { match {$h_Subject:} {\N^Yahoo!
