This article was previously published under Q181947 SYMPTOMS
When you send a message to an X.400 custom recipient over a 1984 mode X.400
Connector, the following non-delivery report (NDR) may be generated:
Your message did not reach some or all of the intended recipients.
Subject: Test
Sent: 1/1/80 1:00 AM
The following recipient(s) could not be reached:
User, Mail on 1/1/80 2:00 AM
The recipient could not be transferred because it could not be
downgraded MSEXCH:MSExchangeMTA:Sitename:SERVERNAME
Additionally, the following event will be generated in the Windows NT
Application Log:
Event ID 175 MSExchangeMTA X400 Service
An error occurred while transferring message C=US;A=
;P=PRMD;L=SERVERNAME-971223150130Z-132, because per-receipt information
could not be downgraded. An X.400 API Association (XAPIA) unable-to-
transfer reason code and unable-to-downgrade diagnostic code were
returned. [MTA DISP:FANOUT 12 147] (14)
CAUSE
The custom recipient was created using a numeric-OR-address and also
contains a private management domain (PRMD) value. This prevents the X.400
address from downgrading from the X.400 88 version to the 84 version.
Consequently, the message is rejected, an NDR is produced, and the above
error is logged.
WORKAROUND
To work around this problem, remove the PRMD value from the custom
recipient mail address. This allows the message to be properly downgraded
from X.400 1988 mode to 1984.
MORE INFORMATION
This problem occurs when you send, over a 1984 mode X.400 Connector, a
message that is addressed to a recipient that contains both a numeric
address, such as X.121 or User Agent numeric ID, and a PRMD value.
In accordance with X.419 Annex B section B 2.8, a numeric-OR-address
containing a PRMD value cannot be downgraded from 1988 to 1984.
