The latest versions of Akonadi and Kmail are causing a strange effect where emails are received normally, but emails are no longer send out and they remain in the outbox.  During startup I also receive an warning that the mailfilteragent is not connected to the DBus (or something similar) and checking the status of the mailfilteragent in akonadiconsole, I see that the status is green, but I do not see the word "Ready" behind it. Restarting the agent gives exactly the same situation. At this moment I am not sure if these are two issues are that they are connected, as that restarting the mailfilteragent doesn't resolve the sending issue. But restarting the full akonadiserver does. 

Reproducible: Always

Steps to Reproduce:
1. Start kmail as normal
2. Create an email and press send
3. Email appears in outbox and is never send
Actual Results:  
The email sits in the outbox and is never send until I restart the akonadiserver (or the full system). No error messages, it just sits there untouched. 

Expected Results:  
Email is send directly
