Szerinte így szebb, jobb stb
A DKIM-nek ki kellett volna térnie a kanonikus alaknál erre is.
Ugyanis ez teljesen szabványos:
Note that the value of a quoted string parameter does not include the quotes. That is, the quotation marks in a quoted-string are not a part of the value of the parameter, but are merely used to delimit that parameter value. In addition, comments are allowed in accordance with RFC 822 rules for structured header fields. Thus the following two forms Content-type: text/plain; charset=us-ascii (Plain text) Content-type: text/plain; charset="us-ascii" are completely equivalent.
Az a probléma itt, hogy a DKIM kanonikus formára hozú algoritmusa nem jól definiált.
