I'm using disconnected imap. Sent-folder is set up correctly. I red in another forum that this is a google issue with imap handling. Reproducible: Always Steps to Reproduce: 1. send a mail via gmail 2. 3. Actual Results: it looks like the mail IS saved despite it says it's not Expected Results: no error message Happend with 4.10 too.
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.
