X400: Gateway Uses Downstream Recipients to Format Message
Last reviewed: October 29, 1994

Article ID: Q115448

The information in this article applies to:


 * Microsoft Mail Gateway to X.400, version 3.2

SUMMARY
When an X.400 message comes into the gateway with one recipient in postoffice 1 (or one recipient with MTA responsibility flag TRUE and the rest FALSE) and multiple recipients at a downstream postoffice 2 (not the gateway postoffice), the X.400 gateway formats the message using all the postoffice 2 recipients for delivery.

MORE INFORMATION
PC Mail does not distinguish between P1 and P2 recipients; the P1 is built on the fly as the message goes from postoffice to postoffice.

The gateway is responsible for all downstream recipients. For reply-all, P2 addresses for which the gateway is not responsible are still in X.400 format and do not need to be converted.

STEPS TO REPRODUCE BEHAVIOR

 * 1) Create a message with one P1 recipient and three P2 recipients.

2. Run the X.400 gateway. 3. Once the gateway puts the message into the mailbag for the downstream

postoffice, use 30DUMP to dump the message in the MAI subdirectory. Notice that it has three "TO" recipients instead of one.
