cyrus & postfix, message being corrupted when viewed by the client

[Bill Kearney]

You've tried two different computers?  Running different mail client
software?

Does the exact same 'bad content' get delivered to an entirely different
mail client program?  Scare up a copy of pine, outlook express, thunderbird
or mozilla suite and see if they all get the same corrupted content.

When you speak of MIME sections all sorts of nonsense can develop.  Let's be
sure that all clients are getting exactly the same bad content before
blaming cyrus.

Likewise, what language and encoding are these messages?  By the .cn TLD one
might gather it's chinese?  Encodings, charsets and languages are mess if
you don't have all the right settings done in the right order.  Make sure
the underlying OS configuration for them is working properly.
