I have troubles sending emails through the send later agent. I'm not sure if it is a bug or a configuration problem and would like some help to diagnose the issue.

Here is what I see: When I compose an email and send it by clicking the Queue Button, the message ends up in the draft folder (as opposed to the outbox as it should, according to the handbook). When the specified time for sending has passed the message simply continues to sit in the draft folder and is never sent. Restarting kontact or even the computer does not help. I can see the message listed in the Send Later Agent though. This is on a current kubuntu installation with kontact 4.13.3

I'd appreciate any help in diagnosing this. Thanks in advance!

This particular issue has been fixed in a newer version of KDE PIM (4.14.2). You should ask your distribution whether there is a way to upgrade to that version.

Thanks for the info, einar!
