455003 - Original incoming email autoflows. The quote back does NOT.

Status: RESOLVED INCOMPLETE

(Thunderbird :: General, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_4; en-us) AppleWebKit/525.18 (KHTML, like Gecko) Version/3.1.2 Safari/525.20.1
Build Identifier: 2.0.0.16

Incoming email is correctly configured with no carriage-returnss. Correctly - it autoflows according to my screen-width or my window resizing.    When auto-quoted back in my reply, the email the message is unreadable by my recipient (or by ME when composing unless by horizontal scrolling to  huge multiple-screen-width infinity.  

Reproducible: Sometimes

Steps to Reproduce:
1. I can think of no action to reproduce.   
2.
3.


Expected Results:  
I would expect the quoted back email to autoflow when quoted back - in the same way as it did when originally received.

Thunderbird on my intel iMac Core 2 (2008) is configured to send emails only in Plain Text.
It happens that the reported manifestation/misbehaviour occurs in received in "some" Plain Text emails.
Could it be that the sender had not enabled "word-wrap" ?
But my Sender is Australia's National Carrier,  Telstra Bigpond.   They should know how to send emails and I haven't had this problem before from them.

Looks like a case similar to bug 387687. Can you go into View > Message Source and check the Content-Type: text/plain and Content-Transfer-Encoding headers? Specifically, watch for "format=flowed" and if "quoted-printable" is set. If the latter is the case, check whether the lines end in "=20" or just "=".

The problem is that if the message contains a full paragraph in a single line, without flowed format set, Thunderbird (correctly) considers it preformatted in the reply and will include it as a single line.

Thankyou kindly for your prompt response.
As initially reported, the originally received email DOES word-wrap/flow correctly when received by Apple Mai.l    It  also behaves similarly under Thunderbird on the Intel iMac.Intel Leopard -  BUT on the latter the issue occurs when the original message is automatically quoted back.

Would this be consistent with your analysis of the earlier bug report 387687 ?
That is to say - it was a flawed email format in the first place ?

You are welcome. A conclusive answer can only be given from the message source,

Could you do that and report back?

Also, I'm not quite sure what "when the original message is automatically quoted back" means, can you be more specific?

While this looks like the same issue mentioned in bug 387687, resolving since no confirmation on the symptoms was provided that it actually is the same.

-> INCOMPLETE
