Hi there, if I try to forward a message with PDF attachments the recipient can't open it due to corrupted file.

Thunderbird 60.5.0. I can reproduce this issue on: Windows 7, Windows 10, Osx 10.x.

I've already checked antivirus and os configuration. Nothing seems to fix.

During the forward I've noticed that the attachament size it smaller than the original file size.

Hi sfhowes, unfortunately this doesn't fix the issue. I've set mail.strictly_mime to true but yet the attachments is broken.

This happens only with forwarding. If I save the PDF locally and attach it to a new message the file is ok.

Anyway I think this has nothing to do with the recipient.
