189206 - Attachment of forwarded message not readable by Outlook Express

Status: RESOLVED DUPLICATE of bug 220646

(MailNews Core :: Attachments, defect)

Description

[Norris Boyd]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212

While using 1.3a, at least one person using Outlook Express was unable to read 
messages I forwarded as attachments. Here's his analysis:

I think I've found it.  It looks like your client is eliding the _filename_,
not just the title.  Your old messages had this type of filename for the
attachment: "Re_[Fwd_participation in wsrp].eml".  The new messages have
"Re_portal integration scoping exercise...", which is missing the .eml
extension.  Someone has gotten a tad too agressive with their eliding in the
version of Mozilla you're using.


Reproducible: Always

Steps to Reproduce:
1. Ensure that in Preferences.../Mail & Newsgroups/Composition has "Forward
Messages" set to "As Attachment"
2. Forward a message to a person using Outlook Express
3. Attempt to read the message in Outlook Express.

Alternatively, just note the missing .eml extension on the forwarded message.

Actual Results:  
The forwarded message was not viewable.

Expected Results:  
The forwarded message should be visible.

The same happened to me with Mozilla 2003021808/Linux-686. May be related to bug
#189977.

This bug pretty much decides it for me to NOT use Mozilla mail at all. Never
mind its general flakiness.

Mail messages forwarded from Thunderbird/Mozilla as attachments
appear to end up as multipart/mixed with an attachment like this:

    Content-Type: message/rfc822; name="New server and questions."
    Content-Disposition: inline; filename="New server and questions."

The attachment shows up, but OE doesnt know what to with it
since the filename doesnt map to the mime type.

When I forward messages as attachments with mutt they look like this:

Content-Type: message/rfc822
Content-Disposition: inline

And this works in OE6

The workarounds are either to not forward as attachments from Thunderbird
or for OE users to view the message source (CTRL-F3 in OE)

While this looks like a bug in OE, that is a large installed base
to not be able to forward attachments to.
