During .docx document sending to Outlook client Kmail loses atachment filename encoding. This information was correct at the sent-mail folder but bad on receiver side, e.g. sent-mail: --nextPart2170179.eotn1eU03S Content-Transfer-Encoding: 7Bit Content-Type: text/plain; charset="utf-8" --nextPart2170179.eotn1eU03S Content-Disposition: attachment; filename="=?UTF-8?B?0KLQtdGB0YLQvtCy0YvQuSDQtNC+0LrRg9C80LXQvdGCLmRvY3g=?=" Content-Transfer-Encoding: base64 Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document; name="=?UTF-8?B?0KLQtdGB0YLQvtCy0YvQuSDQtNC+0LrRg9C80LXQvdGCLmRvY3g=?=" on receiver side: --nextPart2170179.eotn1eU03S Content-Transfer-Encoding: 7Bit Content-Type: text/plain; charset="utf-8" --nextPart2170179.eotn1eU03S Content-Disposition: attachment; filename*=''%D0%A2%D0%B5%D1%81%D1%82%D0%BE%D0%B2%D1%8B%D0%B9%20%D0%B4%D0%BE%D0%BA%D1%83%D0%BC%D0%B5%D0%BD%D1%82%2Edocx Content-Transfer-Encoding: base64 Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document; name*=''%D0%A2%D0%B5%D1%81%D1%82%D0%BE%D0%B2%D1%8B%D0%B9%20%D0%B4%D0%BE%D0%BA%D1%83%D0%BC%D0%B5%D0%BD%D1%82%2Edocx and outlook could not recognize attachment filename. Reproducible: Always
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
