No "Content-Type:"

[Shigeki Uno <shigeki@mediawars.ne.jp>]

Hi, I'm sorry to ask same question again.

I asked you about *Content-Transfer-Encoding* topic the other day and
No problems occured about Encoding MIME e-mails after that.  
(Thanks, Yamaoka-san.)

*But* I said that some e-mails causes *unintelligible sequence of
characters* and these e-mails are encoded by Quoted-Printable.  
I looked into them carefully today again and found that I made an error 
in reports. :-(
  
Following example is e-mail's headers which causes *unintelligible 
sequence of characters*(This is one of them).

I found *Content-Type: text/plain; charaset="iso-2022-JP"* line doesn't
exist. And others which cause *unintelligible sequence of characters*
also doesn't have *Content-Type* line. 

I can read it with _MEW_(Message in the Emacs World) without any problems
but, on the other hand, certainly can't read it with (P)Gnus :-(.  SIGH.

Any suggestions ? 

Thanks.
