XCON: Per-Domain-Bilateral-Info and Third Party Systems
ID: Q157358
|
The information in this article applies to:
-
Microsoft Exchange Server, version 4.0
SUMMARY
By default, Microsoft Exchange Server sends Per-Domain-Bilateral-
Info as an argument in each message that it submits for delivery via
the Microsoft Exchange X.400 Connector.
Interoperability between Microsoft Exchange and certain foreign X.400
systems (some ISODE-based Message Transfer Agents in particular) might
require Microsoft Exchange to be configured so that bilateral information
is not sent with messages.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Microsoft Exchange Service Pack
3. For information on obtaining the Service Pack, query on the
following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
This ability can be configured via the Windows NT Registry as follows:
- Start Regedt32.exe.
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES
\MSExchangeMTA\Parameters
- Add a value name (i.e. click on Edit-Add Value with the Parameters
folder highlighted) called "Do not generate Bilateral Info" as
type REG_DWORD and a hex value of 1. Important: This is case-sensitive
and must be typed exactly as it is printed here:
value 0x1 (0 is the default).
To avoid the loop detection, when a message enters new Microsoft Exchange
Site, the MTA adds Per Domain Bilateral Information to the P1 Envelope to
indicate the names of the Sites the message has passed through. During the
loop detection, if the message reenters a Site, we check this mandatory
Bilateral info to generate an NDR. Some 3rd party MTAs do not understand
the mandatory Bilateral information, hence the registry key.
For additional information regarding the Per-domain-bilateral-information
argument, please refer to the CCITT Blue Book, Rec. x.411, Clause
12.2.1.1.1.2.
