Version: (using KDE KDE 3.3.0) Installed from: Debian testing/unstable Packages When moving mails from one folder to another kmail uploads mails from the folder the mails where moved to and after that downloads it again. Shouldn't it just move the messages on the server? I tried this with a few hundred mails and while uploading the number of messages in the folder list counted down to 0 and after that the whole folder (or maybe just the moved mails?) was download again.
Sure, that would of course be better. But it's just not implemented yet. I'm moving it to a wish, since it really is a wish for an implementation of an optimization.

confirmed on Kubuntu, same versions
I think IMAP does actually not support moving mails on the server, so an upload is necessary. At least I couldn't find the word 'move' in RFC r3501, and I remember that the guy implementing the new Akonadi IMAP resource said that as well.
You are right in a sense that a server side MOVE command is not in rfc 1730 yet it can be emulated by running a server side COPY and then deleting the source. While this may not be perfect, it is much better imho than uploading every message again just because of moving it to a different folder. I know that sylpheed-claws does not require me to re-upload a message when moving mails. Please reopen.
The new IMAP resource for Akonadi implements this with COPY + DELETE, so that will fix this issue once a KMail 2 based on Akonadi is released.
