User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3) Gecko/20030312 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3) Gecko/20030312 Now with SpamAssassin 2.5, it encapsulates the original spam as an attachment so that it can be cleanly analyzed or forwarded to a place like spamcop. However, if the spam is itself a multipart/mime containing HTML Mozilla seems to get lost in two ways: a)it doesn't display the HTML in the attachment b)if the attachment is forwarded, the headers of the imbedded email are mangled or discarded This doesn't seem to happen if the original e-mail had no internal structure of its own. I will attach examples. Reproducible: Always Steps to Reproduce: 1. receive mail with an attachment of e-mail containing HTML 2. open a compose window to send mail to yourself 3. drag the attachment on to the new message 4. send it 5. open the new mail Actual Results: the attachment has been mangled and lost the headers of the original e-mail Expected Results: The attachment sent should be identical to the one received Searching backward, I've found I can make this happen at least as far back as Mozilla 1.1 It's now an issue because spamassassin used to decorate the spam but now it encapsulates the original e-mail as an attachment. This error strips the critical header information needed to track the spammer making Mozilla behave like old versions of Outlook --- gack!

This demonstrates the complaint in the bug tha Mozilla won't display or drag'n'drop the attachment correctly. For display, it only shows the headers. For drag'n'drop it deletes them.

The received e-mail with 118357 (sample spamassassin encapsulation of spam with html) showing that the attachment has been mangled

First, I apologize for the sleazy content of the attachments in the testcases. These are real spams tagged by SpamAssassin. Interestingly, with respect to Comment #1, if you open this link it only displays the attachment's headers not the full body whereas the correct display is done for the link in Commnent #2

I've had a chance to do some more experiments with this and have found that the incorrect display is apparenetly limited to Windows, but that the error with attaching is also found on Linux. I'm attaching two files from Moz 1.3 on Linux showing the attach problem there. I'm also seeing a bug with attaching plain messages, but this is under Windows only and I'll create a separate bug for that.

Summary: mail with attachment which is itself mail containing HTML does not display of forward correctly -- nested MIME problem? → mail with attachment which is itself mail containing HTML does not display(Win) or attach correctly (Win and Linux) -- nested MIME problem?

This is the base from which next mail was created

This is what was received on Linux after drag'n'drop of the attachment in 118954 to a new message. The errors are complex as parts of the attachment were dropped but also parts of the original were included. It's not clear what's going on here.

With respect to Comment #4 about display, the incorrect display occurs only on Windows...Linux gets it right. One should note that the display in Navigator is dependent on how Mail/News View option is set...i.e. Display attachments inline must be set if you want Navigator to show them..looks like Navigator uses Mail/News to render e-mail.

John Gerth: I believe this problem is no longer present in 1.4b. See also bug 189058.

Yes, part (a) (no HTML display) is fixed in 1.4b Part(b) (mangled header when forwarding) is independent of whether the attachment has html or not I will close the bug as a dup of that problem (bug 199995) *** This bug has been marked as a duplicate of 199995 ***
