SYMPTOMS
You send a message with a Compuserve Mail recipient on the BCC line. The message arrives with the Compuserve recipient's name in the To line rather than the BCC line.



CAUSE
This may occur because of the non-conformity to RFC822. Because the TO and CC lines are left blank when addressing the message, the header for the message is considered invalid and the addressee on the BCC line is moved to the TO line to conform to RFC821.



STATUS

This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
