XCON: One Recipient Dropped on Mail to an Exchange DL from X.400 Mail System

ID: Q193961

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

If you send a message from another X.400 mail system to the X.400 address of an Exchange Server Distribution List (DL), one Exchange Server recipient on the DL will not receive the message. The expanded list of recipients is correct, but one Exchange Server recipient will not receive the message. If you ask for delivery receipts when you send the mail to the Exchange Server DL, you will not receive a receipt for this one person on the DL.

CAUSE

A logic error exists in DL expansion if the recipients are using the option to disclose recipients.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
