Issue Encountered:

When email are relayed from the IIS SMTP server to the Microsoft Exchange server, the following error occurs:

Body type not supported by Remote Host

Solution:

By default, the IIS SMTP service advertises 8BITMIME and allows MIME messages to be relayed. However, Microsoft Exchange Server versions 4.0, 5.0, and 5.5 are not able to handle 8-bit MIME messages.

To stop the Windows 2000 and Windows Server 2003 SMTP Service from advertising 8BITMIME, please refer to the following Microsoft Knowledge base article:
