Version: (using KDE KDE 3.5.1) Installed from: SuSE RPMs Courier-imap server (and other IMAP servers) has the feature that mail you put into a a special designated folder is automatically sent by the server. The current support in Kmail feels a bit clunky and incomplete. Currently, you have to do the save-mail-as-draft + move-to-outbox, or configure-fake-sendmail-transport + designate-outbox-as-"sent"-folder. It would be ideal if you could configure it as a transport protocol instead. It would also be much easier for users less knowledgable about the internal details of IMAP.
Just a warning: Don't use save-mail-as-draft + move-to-outbox. Messages which are saved as drafts are a) incomplete and b) contain headers which shouldn't be included in sent messages. I think the other approach is equally bad because the messages in the sent-mail folder also contain KMail-internal headers.
Thank you for your feature request. Kmail1 is currently unmaintained so we are closing all wishes. Please feel free to reopen a feature request for Kmail2 if it has not already been implemented. Thank you for your understanding.
Instead of creating a new feature request, please confirm here if the wishlist is still valid for kmail2.
