flag auto-response emails when posting
We have a reply-by-email feature for our forum that uses Cloudmailin. Sometimes the app gets caught in an infinite loop due to auto-responders. We set the "Auto-submitted" header on our outgoing emails and check for it on incoming ones, but some other mail clients don't set things correctly.
It would be nice if Cloudmailin could analyze emails to see if an incoming email is from an autoresponder. Maybe you guys can do a better job of identifying that than I can.
