Status: NEW

(Thunderbird :: Mail Window Front End, defect)

Description

[ssimon]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 2.0.40607; .NET CLR 1.1.4322; InfoPath.1)
Build Identifier: 

If there are multiple to or cc fields in the header of a message, it is not 
correctly displayed inline when a message is forwareded.  This seems to happen 
with Blackberry users.

Reproducible: Always

Steps to Reproduce:
1. Generate a test message with multiple to or cc fields.  Lacking a 
blackberry, when can achieve this via:
1a. telnet mailserver 25
1b. helo domain.com
1c. MAIL FROM: <youremailhere>
1d. RCPT TO: <youremailhere>
1e. RCPT TO: <anotheraddr>
1f. DATA
1g. From: <youremail>
1h. To: <youremail>
1i. To: <anotheremail>
1j. Subject: a test
1k. press retrun followed by a period, followed by a return
2. Forward the test message to yourself
3. View test message.
Actual Results:  
Only the first To: or CC: recipient is displayed inline.  Opening the 
forwarded message as an attachment results in the message being displayed 
correctly.

Expected Results:  
Display all recipients

I'm not seeing this.  Can you attach a sample email that exhibits the problem?
(Save it as a .EML file and attach it with the Create New Attachment link 
above.)

Attachment: Testcase 1: Sample.eml having Message/rfc822 attachment with multiple To: header lines in source

The attached message exhibits the problem.  Note when rendered as an e-mail
message, the To: field in the forwarded section only show one recipient even
though there are two.  Note when you view the forwarded message it is rendered
correctly.

OK, I am seeing this now.  It does rely on having multiple To: headers, rather 
than multiple addresses in one To: header.  Reproduced with TB 1.6a1-0928 and
1.5b1-0925.

STR:

0 Enable View > Display Attachments Inline
1 Open Testcase 1 (attachment 197786 [details])
2 Look at To: header of attached Message/rfc822 which is displayed inline
3 verify To: headers of attached Message/rfc822 in main msg source (or open the attached message with TB)

Actual result:

2 Only first To: header is shown inline (Shandor...)
3 Source of attached Message/rfc822 has *two* lines of To: headers (as correctly shown when opening the attached msg)

Expected result

When displaying attached Message/rfc822 *inline* in message reader, *all* existing To: headers should be shown (as we do when opening the attached message itself).
