I’m running Windows NT 4.0, SP6a with Exchange 5.5 SP4. I have all the user accounts password protected and the Guest account Disabled. When I open Exchange Administrator, Connections, Internet Mail Service (THIS IS DONE DAILY) and look at the Outbound messages awaiting delivery on the Queues button, there is always anywhere from 30 to 70 items in the queue. None of the items belong to any users and always have <> as Originator. I delete them daily. Any Ideas??
