X400: Err: TMP Variable Not Set Gives WARNING 7 Error

The information in this article applies to:

• Microsoft Mail Gateway to X.400, version 3.2

SYMPTOMS

If the MS-DOS SET TMP variable is not present in the AUTOEXEC.BAT file, version 3.2 of Microsoft Mail Gateway to X.400 generates these error messages:

  15:21:44 WARNING 7 (bodypart typing initialization): Environment
           variable TMP not (or incorrectly) set.
  15:21:44 WARNING 7 (bodypart typing initialization): Using m:x400
           as working directory.

If the user running the gateway does not have sufficient network rights to write to the directory where the TMP variable is set, the gateway is not able to create messages, causing the following errors:

   07:50:39 Extracting message from local message store: 0000003C
   07:50:40 ERROR 3 (creating X.400 message envelope (P1)): opening file:

RESOLUTION

Set the MS-DOS TMP variable to a location with enough disk storage to store the largest X.400 message the gateway can reasonably be expected to receive.
