Precedence: list

The following errata report has been submitted for RFC6376,
"DomainKeys Identified Mail (DKIM) Signatures".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7862

--------------------------------------
Type: Technical
Reported by: Steffen Nurpmeso <steffen@sdaoden.eu>

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.)
