The recipients real name is put into quotes when selecting from addressbook. Reproducible: Always Steps to Reproduce: 1. Compose a new mail. 2. Type the name of recipient in the To: field 3. Select the wished recipient and press enter. Actual Results: The To: field contains the following string (including the quotes): "John Doe" <john.doe@example.org> John Doe is saved without quotes in the addressbook. Expected Results: It should be read: John Doe <john.doe@example.org> So without enquoting the real name of the recipient. In my opinion there is no need for the quotes as there is nothing that is quoted. As far as I can see this is also the suggested format from RFC 5322: https://tools.ietf.org/html/rfc5322#appendix-A.1.1
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.
