Hello,

My mail setting accounts are properly set but since the migration of Arch to kmail 2, i cannot send emails anymore. Anytime i try to send an email i get the following message "There were problems trying to queue the message for sending: Unknown collection.". Note that even not "sending" but "queueing" the email yields the same message. No error message is displayed in the terminal when launching kmail directly. I checked akonadi console but i do not see anything suspicious (though i am not sure what i should look at precisely).

Thanks,

Médéric
