A few versions ago, some genius in Redmond seemingly decided that (a) Outlook obviously would only be used with Exchange and (b) that the form of Message-Id: which Outlook had been using was giving away information about the internal network. So Outlook no longer does Message-Id: headers, leaving it to Exchange to stick one on. Exim's control=submission appeared at about that time. Item (a) above is manifestly untrue. Item (b) above could likely have been worked around by using a hash of the workstation's MAC address on the right of the @ in the Message-Id. [The Microsoft of that time might well have created a new, insecure hash mechanism and patented it.] --John -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
