User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040628 Firefox/0.9.1

When sending a plain text mail, attachments are always
"Content-Disposition: inline;", not "Content-Disposition: attachment;"

On some mail readers (e.g., Apple Mail on OS X, but also others) text files and
some other file types (e.g. .html, .tex) therefore do not appear as attachments
but as inline text and the text file cannot be saved to disk. The same problem
can also apply to images on some mail readers (Lotus). For text files, copy and
paste to a text editor is a workaround in some cases, but it does not help if
there is a large number of attachments, if it is unclear where one attachment
ends and the next one starts, or if the filenames of the attachments must be
accessible to the user (e.g., when sending several files containing program
sourcecode as attachments).

I think that some statements discussed as Bugzilla Bug 55657 refer to this
problem, but it has not been properly understood and handled. 

It is the same problem with Mozilla 1.5 and 1.7


Reproducible: Always
Steps to Reproduce:
1. create a new mail (Preferences: all domains plain text)
2. attach a file by dragging into the attachment box
3. send mail
4. view mail as source on the recipient's mailer

Actual Results:  
Example mail received (as raw source)

Hallo All,




Expected Results:  
The same with
"Content-Disposition: attachment;"
This should allow me (and other reciepients) to save the attached files to disk.
To change the attachment disposition type, you can add this to prefs.js:

  user_pref("mail.content_disposition_type", 1);

A text file will still be viewed inline in Mozilla, unless the View menu option 
is turned off.
