Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you! Yes, seems to still be the case, exactly as before, saving the same message from inside kmail and from outlook webmail gives extra newlines between mime parts. |
KMail mangles newlines in a multipart message. This causes siganture verification to fail. I believe this is caused by parts in multipart messages that do not end with a newline. The attached file shows the problem. It is a message that has the following structure: multipart/signed multipart/mixed multipart/related text/html image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg image/jpeg >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> application/pdf application/pkcs7-signature KMail adds a newline after the end boundary of multipart/related and before the boundary of multipart/mixed (in the marked place).
