Today (at least for us) we were notified of a Google change where any emails being received with multiple headers (ie. To: alex@example.com To: john@example.com NOT To: alex@example.com, john@examle.com) will now be rejected by Google. We've been given a month before Google implements this, without any tool that tells us who is sending these.
So the question posed in several communities is: is there a tool to find these malformed emails so that we can either A) notify the sender/vendor that they'll be rejected unless they reconfigure their email system or B) internal systems that may be using this malformation and we need to either update those systems completely or just reconfigure them.
(rhetorical) I haven't looked at the NDA documentation yet, but I'm not sure this type of change would even be in there. (rhetorical)
