XFOR: Garbled Attachments Between Exchange 4.0 and 5.0 IMCs

• Microsoft Exchange Server, version 4.0

SYMPTOMS

When you send multiple attachments across Internet Mail Connectors (IMCs) between a computer running Microsoft Exchange Server 5.0 and another computer running Microsoft Exchange Server 4.0, every other attachment will be garbled if the IMCs are configured to transfer messages in binhex.

CAUSE

The binhex decoder consumes the blank line that separates each binhex bodypart. If the message contains consecutive binhex bodyparts with no blank lines between these bodyparts, every second binhex bodypart is copied to PR_BODY undecoded.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
