This is a real world of narisumasi:
http://headlines.yahoo.co.jp/hl?a=20120608-00000510-san-soci

Ms. 菊地直子 lives under the name 櫻井千鶴子, which is not hers.

Because the Japanese tries to explain narisumasi me-ru in simple way,
and some correctness must be traded off for simplicity.

This could be a cause of being classified as narisumasi.

But if you could send the mails' headers here, we can judge technically.

However, this is what google's mail judge an email as *spam*
- Originated IP of the email is in a blacklist.

and judges and email as *phising* if "From:" field in email header has
no relation with the IP/domain
he mail comes from (I guess)

And I think mail.yahoo.co.jp's scoring systems handles in the same way.

mail.yahoo.co.jp supports SMTP
(http://help.yahoo.co.jp/mail/mailsoft/mailsoft-01.html)

And a mail sent using yahoo's SMTP but the From: field does not
include yahoo.co.jp,
I think it could be judged narisumasi.

Just some guess :) I think sysadmins who work with mail servers will
have more accurate answers.
