SYMPTOMS
Simple Mail Transfer Protocol (SMTP) messages are not being encoded properly when senders send messages to recipients using Rich Text Format. The messages are being delivered in Raw Text.
CAUSE
The code that scans for 8-bit characters in the Subject string has a logic error such that if the only 8-bit character in the string is the last character, the code does not detect it as such. When "UseRTFText" is true, the stream passed to rcScan() to scan for 8-bit characters is the incorrect stream.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 4.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
Many content types are natively formatted as 8-bit character or binary data. Data formatted in this way cannot be sent using SMTP, RFC-821, as the transport protocol. As mentioned earlier, RFC-821 limits messages to 7-bit US-ASCII with lines no longer than 1,000 characters. So, a method for encoding such data as 7-bit US-ASCII is needed. The encoding formats do not describe the data itself, but only the encoding used to transport the data.
