134038 - Incorrect encoding of words in header fields (RFC 2047)

Status: RESOLVED INVALID

(MailNews Core :: MIME, defect)

Description

[Claus Nielsen]

According to RFC 2047:

[--- QUOTE (near top of page 7 of RFC 2047) ---]

Ordinary ASCII text and 'encoded-word's may appear together in the
same header field.  However, an 'encoded-word' that appears in a
header field defined as '*text' MUST be separated from any adjacent
'encoded-word' or 'text' by 'linear-white-spac

[---- END OF QUOTE ----]

I occationally recieve messages written in Mozilla mail with headers
like this:

X-Mailer: Mozilla 4.78 [en] (X11; U; Linux 2.4.9-31 i686)
Subject: Re: [NOVICE] =?iso-8859-1?Q?Hj=E6lp?=, grafikken spiller ikke!

The comma following the encoded word in the Subject causes my MUA (Evolution) to
NOT decode it - and rightly so as it isn't correctly encoded according to RFC 2047.

Ahem... What you describe seems to be caused by Netscape 4.78, not Mozilla.

I just tried with Mozilla 1.3b and it seems fine:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.3b) Gecko/20030210
Subject: pokus =?ISO-8859-2?Q?as=F9=EC=B9qw=2C_asd?=

Marking INVALID.
