The answer for your question is NO. I saw this mail with Mozilla
Thunderbird and found the filename is also "44新規学習ニーズ対応プログラム支援経費=?ISO-2022-JP?B?WxskQjpOQnJAKRsoQl0bJEIhS"

I agree with your opinion. Adding '=?=' is not cool.

Here is the header of the mail.

User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; ja-JP; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)

And here is the header of the part in concern.
