377370 - Encoded Umlauts and commata in From will result in address breakup

Status: RESOLVED DUPLICATE of bug 254519

(Thunderbird :: Mail Window Front End, defect)

Description

[Peter Bieringer]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.0.10) Gecko/20070313 Fedora/1.5.0.10-5.fc6 Firefox/1.5.0.10
Build Identifier: Thunderbird 1.5.0.10 and 2.0b2

If encoded Umlauts and commata are used in From a very unexpected behavior occurs:

The From is not displayed well and even on reply, a second line is produced

Reproducible: Always

Steps to Reproduce:
1. Create test mail:

$ cat tmp/mail-umlaut.txt
From: =?iso-8859-1?Q?Sure=F6name=2C_Forename__Dr=2E?= <[e-mail]>
To: "Peter Bieringer" <[e-mail]>
Subject: Umlauttest

Testmail containing Umlaut and commata in From:
<<END

2. Send mail
$ cat tmp/mail-umlaut.txt | /usr/sbin/sendmail [e-mail]

Results:
a) Main mail panel / sender column:
Is:     Sureöname
Should: Sureöname, Forename Dr.

b) Mail window / From:
Is:     Forename Dr. <[e-mail]>
Should: Sureöname, Forename Dr. <[e-mail]>

c) after hitting the reply button / recipients:
Is:     To: Sureöname
        To: Forename Dr. <[e-mail]>
(2 entries!!!!)

Should: To: Sureöname, Forename Dr. <[e-mail]>



This problem was found by receiving a valid e-mail from an Outlook client.

Note that Outlook Express and also the IMAP client of a Nokia Communicator proper displays and handle this From address (showing "..." around).

Note that 2.0.0.0rc1 the behavior changed a little bit:

a) Main mail panel / sender column:
Is:     Sureöname
Should: Sureöname, Forename Dr.

-> same like in 2.0b2 and 1.5.0.10


b) Mail window / From:
Is:     Sureöname, Forename Dr. <[e-mail]>
        _________  ______________________________
(break in underlining)

Should: Sureöname, Forename Dr. <[e-mail]>
        _________________________________________
(no break in underlining)

c) after hitting the reply button / recipients:
Is:     To: Peter Bieringer <pbieringer.de>
Should: To: Sureöname, Forename Dr. <[e-mail]>

The reply address handling is completly broken!
