According to email RFC's, Message-ID is a required header. It's also used for grouping by conversation (Outlook term). I wouldn't remove it. -----Original Message----- From: Danny [mailto:nocmonkey@xxxxxxxxx] Sent: Thursday, September 09, 2004 4:41 PM To: [ExchangeList] Subject: [exchangelist] Message-ID Header - is it essential for proper email flow? http://www.MSExchange.org/ Is the Message-ID header created by Exchange (using 2003 here) of any importance for proper mail flow? I have a way to remove it at our mail gateway for outbound (to external email addresses) emails. This one: Message-ID: <randomnumbersandletters@xxxxxxxxxxxxxxxx> Thank you, ...D ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: michael@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
