351399 - Required attachments should not be turned to inline

Status: RESOLVED DUPLICATE of bug 65794

(Thunderbird :: Message Compose Window, defect)

Description

[Jean-Francois Dockes]

User-Agent:       Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.8.0.2) Gecko/20060423 Firefox/1.5.0.2
Build Identifier: version 1.5.0.5 (20060905)

Thunderbird will change a request to attach a .txt file into an inline part (content-disposition: inline). I believe this to be a bad idea for several reasons:
- This interprets and changes the user request.
- The text file may have special formatting (ie checksummed licence file), where blank space may be significant. The recipient will have trouble recovering the exact data if his mua doesn't have an easily accessible option for saving inline parts to files.
- The character set of the file is unknown and this may result in garbage display for the recipient.
Agreed,none of these problems exist if the recipient's mua is thunderbird. But there are other mail tools that don't behave so well given an inline part with a file name.

Reproducible: Always

Steps to Reproduce:
1. Attach a text (.txt) file to any message

Actual Results:  
Content-Type: text/plain;
 name*=ISO-8859-1''%E9nerv%E9.txt
Content-Transfer-Encoding: quoted-printable
Content-Disposition: inline;
 filename*=ISO-8859-1''%E9nerv%E9.txt

Contenu de l'=E9nerv=E9

Expected Results:  
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment;
 filename*=ISO-8859-1''%E9nerv%E9.txt

Contenu de l'=E9nerv=E9
