XADM: Messages Sent with MIME/JIS Encoding May Not Be Readable

• Microsoft Exchange Server, version 5.0

SYMPTOMS

When your Microsoft Exchange Server is configured to use MIME/JIS (Japanese Industry Standards, code set for Japanese character), some messages that you send to Simple Mail Transfer Protocol (SMTP) users may not be readable.

CAUSE

With Microsoft Exchange Server set up to use a MIME/JIS configuration, messages are expected to be encoded with 7-bit data. However, if an invalid character is included in the message, the message will be encoded Quoted- Printable. Some mail readers do not support Quoted-Printable, and if they receive messages encoded in Quoted-Printable, the messages will not be readable.

Some applications generate the character 0x9520, which is an invalid CP932 character. If you copy this character, paste it into a Microsoft Exchange message, and send it to an SMTP user, this problem will occur.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0.
