'Evolution' email cleint error after upgrade from F14

'Message was sent, but an error occurred during post-processing.
...Failed to append to mbox:///..../local#Sent: Cannot get folder 'Sent': folder does not exist. Appending to local 'Sent' folder instead.

It seems to be a fault alarm. Also, sometimes saw POP3 error, followed by message: 'Success'.

I solved a similar problem by doing:

cd ~/.local/share/evolution/mail/local
touch Sent

Thats it! The message stopped displaying after that
