Please do not force .txt and HTML attachments to have content-dispostion=inline

One result of this is that Lotus Notes does not handle Netscape attachments of
.txt and HTML files. It places them inline, so they are not accessible as
attachments.

Lotus knows this. Here's what they say.

``The problem is the result of the way the Netscape SMTP client sends the
message. Because the Netscape client uses "Content-Disposition=Inline" for *.TXT
attachments and not "Content-Disposition=attachment", all text attachments will
be expanded upon receipt of message. Domino 4.6x follows the RFC standards more
closely... Netscape client and SMTP MTA 1.1 do not follow the RFC standard on
attachments as closely. The Content Disposition of an attachment will determine
if it is passed as an attachment or inline (for example, .TXT will pass as
inline).''

If Lotus is right, I do not understand why Netscape has not made fixing this
a priority. If Lotus is wrong, I would appreciate a brief explanation that I
can take back to them.

I don't know if I think Lotus is right, but it would be nice to provide some
prefs or something to make this settable for people who know they need it in
order to interoperate with some other mail system.

Another data point: Outlook Express seems to always use "content-disposition:
attachment"

Changing content-dispostion for an attachment, could be added to a context menu 
to the attachment box in the compose window.
The context menu could look something like:
Advanced->Content-Dispostion->Inline       [ ]
                              Attachment   [x]

Probably, this will resolve that you add the following line to prefs.js.

  user_pref("mail.content_disposition_type", 1);

If you want changing UI. please open new bug.

Comment 9

[Ben Bucksch (:BenB)]

Bug 67160 for the UI.

Comment 10

[Henrik Gemal]

the correct new UI bug is bug 66915

Kato, please let me know if this is a worksforme or if you fixed it by adding a
hidden pref "user_pref("mail.content_disposition_type", 1);" to the product.

Using the build 2001-09-04 on win, mac and linux and adding editing the 
prefs.js file, I now see content disposition attachment on .xls .pdf .zip & .js 
files that showed dispositon as inline before the pref.js edit.  This is fixed 
for backend, frontend is a different bug. Verified
