SYMPTOMS
When you send e-mail using the Microsoft Exchange Server version 5.0 Internet Mail Service (IMS), the X.400 address may be encapsulated into the Mail From field.

This occurs when a DDA is specified on the sending mailbox's X.400 address with type: MSXCX500. This occurs even if a valid SMTP proxy address is specified for the mailbox.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
