Version: 1.6.0 (using KDE 4.7.0) OS: Linux If one has a file in an IMAP's "sent" folder and deletes it, akonadi/kmail2 downloads it from the sent folder and then uploads it to the IMAP's trash folder. This is slow and wasting bandwith. Reproducible: Always Steps to Reproduce: Put a large message in your IMAP'S draft folder Delete it, i.e. let kmail move it to the IMAP's trash and watch your network-traffic Actual Results: A lot of network-traffic that downloads/uploads the email from the server to the server Expected Results: Use IMAP commands to move message on the server without down/uploading it. Something like select source copy trash mark copied message as deleted expunge OR with UIDPLUS expunge only the one deleted message.
Should be specific to KMail, the resource has all the wiring to do the move server side.
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.
