A Microsoft Exchange 2000 Server recipient may receive an e-mail message that is not formatted correctly. Or, an Exchange 2000 recipient may receive a non-delivery report (NDR) after the recipient sends a message. These problems occur when all the following conditions are true:
This problem occurs because the extended characters that are used in international character sets are not included in the ASCII 7-bit character range. Therefore, an e-mail message that contains more than 998 characters cannot be wrapped, and the characters are labeled with incorrect 7-bit encoding during transport to the final mailbox server.
To resolve this problem, obtain the August 2004 Exchange 2000 Server Post-Service Pack 3 Update Rollup.For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
The default MIME encoding in Exchange 2000 Server is 7-bit transfer encoding. The MIME encoding in some Asian languages must be set to an encoding method that is different from 7-bit encoding to wrap lines of text that contain more than 998 characters.
After you apply this rollup, you can use registry values to set the MIME encoding method in the following registry subkey:
Use the values that are listed in the following table.
The default value of 0 for 7-bit encoding is used if the registry subkey value contains a value that is not listed in this article. The hotfix to resolve this issue permits the administrator to use the registry to select the transfer encoding for all the character sets that are affected. The Administrator must set the encoding method correctly depending on the clients and their encoding capability.
