  • Microsoft Mail Gateway to X.400, version 3.0

SUMMARY

The X.400 gateway is actually a series of modules that belong either to the Proprietary X.400 gateway or to the 1984 standard X.400 message handling system (MHS).

MORE INFORMATION

All files are stored on the server; some are data files and some are executable files. The executable and data files include software components that are proprietary to the mail store, proprietary to the gateway, and standard to the X.400 message handling system. The following is an illustration:

The Microsoft Mail database contains the mailbox for the gateway, forwarding postoffices and the users for that postoffice. The message store contains the outgoing queue. The Microsoft message store and directory services are proprietary and are not X.400 compliant. The messages are currently in the following mail database directories: 

   MAI
   KEY
   MBG
   ATT
The gateway is the module that is defined as the process of interaction between the Microsoft mail store and format, and submission to the 1984 X.400 standard format. The gateway primarily changes the formats, encoding, and addressing of the messages. The gateway is proprietary and not X.400 compliant; however, the gateway converts messages to the X.400 compliant format and then submits the messages to the X.400 compliant message transfer agent (MTA). The gateway uses temporary work space to convert the message formats. 

   BODYPART.CFG
   ADDRCONV.CFG
   MAPTBL.IN
The X.400 MTA is a 1984 MTA standard compliant. The ROUTE.CFG table is part of the MTA: 

   ROUTE.CFG
   OUTCNCT.CFG
   INCNCT.CFG
   MTA.CFG
