I've received an email containing an HTML but Mozilla can't display it.  I saved
it in a file and found that Outlook Express can display it.  What's the cause of
the problem?  The MIME part is wrong (because it lacks several headers)?  Or
Mozilla isn't programmed yet for this kind of MIME format?

Reproducible: Always

Attachment: Problem mail with strange MIME

This attached contains a real case, well, almost.  First I've changed the
sender's address (that I suppose wouldn't affect anything).  Second, the MIME
encoded HTML part isn't the original one but a test case that I replaced into
it.  I've tried again with Mozilla and Outlook Express and still got the same
result.

After some trials and errors, I've found out the cause:
in the email header, if we remove the following line, Mozilla is able to display
the content.

Content-Type: text/html;charset=big5

So, the problem is the email or Mozilla?

the email is invalid!

The mail has:
Content-Type: text/html;charset=big5
Content-Type: multipart/mixed; boundary = b07bac4987f1ca929d60485ad5ed22bb1

the mail cannot be both!

The charset header should have been moved to the part ifself like this:

-------------
Content-Type: multipart/mixed; boundary = b07bac4987f1ca929d60485ad5ed22bb1

This is a MIME encoded message.

--b07bac4987f1ca929d60485ad5ed22bb1
Content-Transfer-Encoding: base64
Content-Type: text/html;charset=big5

--------------

then it work fine!

So the problem is a invalid email!
