When Kmail quits while composing an e-mail, it nicely reappears next time you start the application, so you can finish editing and send it. However, a copy of it is not saved in the 'Sent' folder (although it's received by the people you sent it, and confirmed by receiving replies to that e-mail). Reproducible: Always Steps to Reproduce: 1. Write a new e-mail 2. Restart Kontact 3. Sent the e-mail Actual Results: It's missing in the 'Sent' folder, so you lose the copy of the e-mail for your own records Expected Results: It should appear in the 'Sent' folder, as it usually happens when you send any e-mail This bug doesn't seem to be universal though, while it always happens with my university disconnected IMAP account, it doesn't affect my gmail disconnected IMAP account. I ignore why
i can confirm this behavior using IMAP
kde 4.12 with akonadi server 1.11.0 (gentoo linux)
I can confirm this bug on Arch Linux with akonadi 1.11.0 and kmail 4.12.1 (= Arch Linux with latest updates). I used this IMAP setup with my four mail accounts with Gnome-Evolution for years, but never lost a sent mail, so I assume it is a kmail2/akonadi issue. IMHO the problem is that IMAP connections are not reliable, so sending mail should be embedded into a transaction: The local sent mail shall only be deleted, if a successful move to the remote IMAP sent-mail folder is confirmed. My current workaround is a filter, that also copies all sent mail to the local sent-mail folder, but I already lost quite some mail, so I rate this bug as critical. With regards to Google mail, at least Google Apps for businesses copies every sent mail to the sent mail folder, and this is done by the Google server, so with Google Apps it is not advised to copy sent mail by the mail program, otherwise you get double mail (if mail client copying works correct). Maybe it is the same with Gmail?
this bug is still valid on KF5
(using kmail 15.08.2 preview)
This bug also applies to mails temporarily saved as draft. I have observed, that the e-mails are saved, but not in the IMAP-Sent folder. Instead they are saved in "local folder"s sent folder.
I can confirm this bug on Debian Stretch with KMail 4.14.10.
original trigger (close, re-open kmail) of this bug is still valid for kmail2 5.3.1 however, for draft e-mails this problem seems to be gone.
I cannot reproduce this issue anymore
