these days any kown mail client in case of IMAP copies the message after successful sending via APPEND to the sent folder on the IMAP server - if kmail as default stores it only in a local folder file a bug against kmail hence you can even configure in which IMAP folder sent messages should be stored which is one of the biggest problem because every random client handles this different instead look if there is a "Sent" folder use it and display the locale name unindependet of the servers name mix different clients and in case of Apple mail.app and iPhones with different patchlevels and you will see a ton of different named sent-folder until you configure any device to use the same and remove the orphans the XLIST capability promises to solve this problem but it will take years until any relevant client is supporting this and only god knows how to act in the situtation where you still have 5 different sent-folders - so in the real world expect the problem exists the next 5 years http://www.limilabs.com/blog/imap-list-xlist-and-lsub _______________________________________________ transfer it only once to the MTA and from there to the sent-folder is more or less impossible - most mail systems deliver messages via LMTP to dovecot or whatever MDA and in that case have no predictable way to put it in the sent folder serverside, at least not if you keep in mind that people access their mail with different clients at the same time in days of smartphones, tablets and whatever clients acess the same account at the same time
