XFOR: Internet Mail Service Is Not Properly Encoding Messages (178709)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q178709 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.
