The following errata report has been submitted for RFC6857,
"Post-Delivery Message Downgrading for Internationalized Email Messages".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6573

--------------------------------------
Type: Technical
Reported by: Kaspar Etter <me@kasparetter.com>

Section: A

Original Text
-------------
   From: =?UTF-8?Q?DISPLAY-LOCAL?=
         =?UTF-8?Q?NON-ASCII-LOCAL=40example=2Ecom?= :;

Corrected Text
--------------
   From: =?UTF-8?Q?DISPLAY-LOCAL_?=
         =?UTF-8?Q?NON-ASCII-LOCAL=40example=2Ecom?= :;

Notes
-----
Taking the original text from Errata 3955 (https://www.rfc-editor.org/errata/eid3955), the two encoded-words decode to: DISPLAY-LOCALNON-ASCII-LOCAL@example.com :; (According to section 6.2 of RFC 2047, linear whitespace between adjacent encoded-words is ignored.) This is clearly not desirable and thus a space should be encoded at the end of all display names in appendix A.

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
