292331 - inexistent smime.p7m shown (or eml atta)

Status: VERIFIED DUPLICATE of bug 182627

(Thunderbird :: Mail Window Front End, defect)

Description

[Ralf Hauser]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Admitted the attachment 182156 [details] ("corruptSigned.eml") is based on a bug in
microsoft outlook (send a signed message, open for resend and then disable
signing and send again). But I guess even if Thunderbird receives corrupt MIME,
it should robustly display what it reasonably can and not dream up attachments
that do not exist.

Reproducible: Always




if as per bug 292329, you also have difficulties opening the attached message
from the disk, just attach it as .eml and mail it to yourself.

Then bug has slightly different features: when opening the attached
corruptSigned.eml, it will recursively show itself as attachment...

Using Thunderbird version 1.0.2 (20050317)

This is also a dupe; it's the same bug as 292329.  The message is not corrupt, 
by the way, it just has an unusual Content-Type header.

maybe "corrupt" is the wrong word for it, but AFAIK a "quoted-printable" should
always be together with a "charset", otherwise, e.g. Umlauts get wrong.

BTW, having both in Outlook and Thunderbird "?" or "ü"instead of "ü" was how we
started to notice that something is "unusual"

It's true that the message should have a charset, since it's encoded with UTF-8 
and the default (if no charset specified) is US-ASCII.  It's also true that in 
Thunderbird, the "Universal Autodetector" is not available (bug 261485).

However, that has nothing to do with the display of the "attachment."

also, declaring a message
<<smime-type=signed-data;
name="smime.p7m">> and neither adding a signature nor using the encodings
tyically found with p7m is kind of misleading (admitted, thunderbird does detect
that it's not signed)
