Description Bernhard E. Reiter 2006-05-16 20:20:59 UTC

Version:            (using KDE Devel)
Installed from:    Compiled sources

Here is a sniplet from an email I have created with KMail:

From: "Reiter, =?iso-8859-1?q?B=F6rnhard?=" <bernhard@intevation.de>
Date: Fri, 28 Apr 2006 17:13:13 +0200
User-Agent: KMail/1.7 (proko2 branch after 2.1.0)

The From: line violates RFC2047:

http://www.faqs.org/rfcs/rfc2047.html:

 + An 'encoded-word' MUST NOT appear within a 'quoted-string'.

And RFC2822:

 quoted-string   =       [CFWS]
                        DQUOTE *([FWS] qcontent) [FWS] DQUOTE
                        [CFWS]

DQUOTE being ascii 34.

This was mentioned for attachments in bug#41558
as far as I can see, but apparently not fixed for the from:

Thank you for taking the time to file a bug report.

KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
