Description Albert Astals Cid 2018-04-23 09:29:36 UTC

I have a few emails that have attachments in the form of

Content-Disposition: inline;
filename=BusinessCardSheet2nd-edition1.pdf
Content-Type: application/pdf;
x-unix-mode=0644;
name="BusinessCardSheet2nd-edition1.pdf"
Content-Transfer-Encoding: base64 

And they don't have the "have attachment" flag set, meaning that when i change the filter to show only emails with attachments they do not show up.

I can confirm this too but it might only be limited to email sent from Apple software.

if you hit ctrl-alt-d, it shows the structure with all the correct attachments

This is most likely because of “Content-Disposition: inline”: this is not an attachment! The program that composed the mail is saying: “You should display this inline.” Of course for a pdf, this is going to be difficult (perhaps the Apple MUA can?) It is entirely like inline jpegs in html mail. But now, instead of a jpeg, there is a pdf. I guess it's entirely correct MIME.

My take is that kmail should treat inline MIME parts that it cannot display as attachments.

Could you save such a mail, remove any personal info from it, and attach it here?
If the developers get to this bug, that would be convenient.
