Huh? If you assign an smtp address to a DL with no members, the message just disappears & no NDR is sent. or am I just confused 'cause I've been sick? -Michèle Immigration site: http://LadySun1969.tripod.com Our new 2001 Miata: http://members.cardomain.com/bpituley Tiggercam: http://www.tiggercam.co.uk --------------------------------------------------------- If insane people had more money they would just be eccentric. --------------------------------------------------------- -----Original Message----- From: Steve Jacobson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 17, 2001 6:28 PM To: MS-Exchange Admin Issues Subject: RE: How can you reject messages in Exchange 5.5?-I guess you can't >From the comments here, it seems that you can't set up exchange 5.5 to do what I was originally looking to do: Either reject outright a message without a mailbox, or simply not send an NDR for a message without a mailbox. This seems to be what I am hearing? Is this correct? The idea of dropping the messages in a black hole won't do what I wish: an NDR will be sent to the sender.
