The 9405 event is from the Field Engineering category: An unexpected error has occurred which may cause the MTA to terminate. Error: Bad secure on object 2589. [BASE XFER-IN 28] (16) CAUSE ===== Access to a connector such as the Internet Mail Service, located on the affected server, is limited using distribution lists (DLs). Because of this restriction, transferred messages have to be checked against this access limitation and the DLs have to be expanded.
