Steps to reproduce:

When trying to forward a specific message (the message is in the atachment of the bug report) in an attachment the file doesn' t attach at all, probably because it shows that the file has unknown size. And it doesn't recognize the file as pdf.

Actual results:

the file didn't attach

Expected results:

the file should attach

@Francesco: Replacing multipart/related with multipart/mixed (as you suggested in bug 1872243#c3) solves the problem reported in this bug. Does that mean, this is also a duplicate of bug 408114 ?

Comment 9

[Francesco]

If you download attachment 9252627 [details] and look for lines containing "content-type" you get:

Content-Type: multipart/related; type="text/html"; charset=UTF-8; boundary="rD8T1nK2Dh1lgBeoVip0=_jnkyAsQof7ws"
Content-Type: text/html; charset="UTF-8"
Content-Type: application/pdf;

So the attachment sits inside a "multipart/related" when it should be "multipart/mixed". So yes, it's a dupe of bug 408114.
