  ここで適用されるのは (3) の方です。

|    (3) As a replacement for a 'word' entity within a 'phrase', for example,
|        one that precedes an address in a From, To, or Cc header.  The ABNF
|        definition for 'phrase' from RFC 822 thus becomes:
| 
|        phrase = 1*( encoded-word / word )
| 
|        In this case the set of characters that may be used in a "Q"-encoded
|        'encoded-word' is restricted to: <upper and lower case ASCII
|        letters, decimal digits, "!", "*", "+", "-", "/", "=", and "_"
|        (underscore, ASCII 95.)>.  An 'encoded-word' that appears within a
|        'phrase' MUST be separated from any adjacent 'word', 'text' or
|        'special' by 'linear-white-space'.

  また、draft-ietf-822ext-mime-hdrs-00.txt では

|    These are the ONLY locations where an 'encoded-word' may appear.  In
|    particular:
  ...
|    + An 'encoded-word' MUST NOT appear within a 'quoted-string'.

というコメントが加わっていて、「"」を含めて encode しなければいけない
ことが明確になっています。

  ほかに impost について気付いた点ですが、

と encode されてしまいましたが、「KOBAYASHI」を含めて encode するのだ
と思います。
