231187 - Plain text fails to wrap when sent, succeeds on "Send as New"

Status: RESOLVED DUPLICATE of bug 197130

(Thunderbird :: Message Compose Window, defect)

Description

[Ryan Reich]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7a) Gecko/20040114 Firebird/0.8.0+
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7a) Gecko/20040114 Firebird/0.8.0+

Thunderbird's implementation of line wrapping is a little buggy, in that if I
tell it to wrap text messages, it will do so in the compose window but send the
unwrapped version.  Strangely, if I then go to the "sent" folder and resend the
message using "Send as New" without touching the body, it will properly wrap it
the second time.  I have only tested this for newsgroup messages since I don't
use Thunderbird for mail.

Reproducible: Always

Steps to Reproduce:
1. Make sure that you do not send HTML by default.
2. Write a message with lines long enough to wrap in the compose window.
3. Send it, observe that both the copy that goes to the newsgroup and the one in
the "sent" folder are faulty.
4. Go to "sent", re-send the message as new, observe that both copies are now
correctly wrapped.

Actual Results:  
I get one unwrapped, one wrapped message in both the "sent" folder and on the
newsgroup.

Expected Results:  
I should get a correctly wrapped message the first time.

More experience has shown that Thunderbird's "Rewrap" commannd (under Edit in
the compose window) is also faulty.  It correctly wraps the new text the first
time, but incorrectly wraps any quoted text: if it had been wrapped before,
after Rewrapping the quoted text is inconsistently unwrapped.  When sent, the
message contains some very long lines in quoted text and some wrapped lines, and
all wrapped lines in unquoted text.

The wrapping is working as intended.  You are seeing the effects of 
format=flowed, which is on by default in Mozilla & TB.  Please refer to bug 
168420 and the mini-FAQ attached to that bug; information on disabling f=f is 
found there, if desired.

The fact that Edit As New breaks the f=f formatting for a message is a problem; 
that's bug 155622.
