Type: Technical
Reported by: Steffen Nurpmeso <[email protected]>

Section: 3.4.2

Original Text
-------------
[..]

Corrected Text
--------------
[insert after item 2]

Due to de-facto implementation practice, the term WSP of the following two 
items, as well as in the part that refers to after the separating colon (the 
field body) in the third, has to be interpreted differently,
and must include all US-ASCII whitespace characters, namely %d9 (HT), %d10 
(LF), %d11 (VT), %d12 (FF), %d12 (CR) as well as %d32 (SP) [?](the isspace(3) 
set of characters in the ISO C "C" locale)[/?]

Notes
-----
As written.
The behaviour *could* originate in a partial misunderstanding of the Sendmail 
milter protocol, which is often used to implement DKIM; this protocol *may* 
send header continuation lines separated by lone LF bytes, instead of CRLF.
(Thanks to Claus Assmann of esmtp.org for this in-between-the-lines reading.)
