DOCUMENT:Q169299 19-DEC-1999 [exchange] TITLE :XCON: HP Openmail Returns a Loop Detected NDR to Exchange PRODUCT :Microsoft Exchange PROD/VER:winnt:4.0,5.0,5.5 OPER/SYS: KEYWORDS:kbusage exc4 exc5 exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== When you send a mail message to an HP Openmail message transfer agent (MTA) over an X.400 88 Connector in X.410 RTS mode (84), you may receive a non- delivery report (NDR) indicating that the originator of the message detected looping. Note that the recipient on the HP system does receive the message. CAUSE ===== This behavior may happen if you select the default "Use the GDI from Site Addressing" option on the Advanced tab of an X.400 Connector and the remote MTA is in fact in a different Private Management Domain (PRMD). RESOLUTION ========== To resolve this problem, specify a Global Domain Identifier (GDI) on the Exchange Server X.400 Connector that matches the remote system's GDI: 1. In the Exchange Server Administrator program, select the X.400 Connector corresponding to the remote MTA: Org/Site/Configuration/Connections/ 2. On the File menu, click Properties to edit the properties of this X.400 Connector. 3. On to the Advanced tab, select the "Use the GDI specified below" option. 4. Set the Country, ADMD, and PRMD values according to the remote site values. The GDI, which is composed of three X.400 attributes (Country, Administration Management Domain, Private Management Domain), now contains the values of the remote site's attributes. This new setting will eliminate the loop detected NDRs. MORE INFORMATION ================ When you select the "Use the GDI from Site Addressing" option in the advanced property page of an X.400 Connector, the Internal X.400 Trace Information is conveyed to remote MTA instead of being removed from P1 envelope. In some cases, for example if you have asked for a delivery receipt, this trace information causes a loop detection NDR to be sent back to Exchange user: Your message did not reach some or all of the intended recipients. Subject: Test message to HP Openmail Sent: 01.07.97 15:13:05 The following recipient(s) could not be reached: /c=c/a=Admd/p=Prmd/o=Org/s=Surname/g=GivenName on 01.07.97 15:16:41 The recipient was detected looping within the message transfer service.
