Sending with kmail 3.5.13.1

Hi For sending with kmail I have to select the "via" each time whether from the addon to the uparrow icon in the composer window or subsequently from the File > Send queued messages > via. How do I set it to just click on up arrow icon in composer window and have it sent from outbox, just have one sending account. I don't remember any problem setting that way before and single click send is the habit of quite a few years. In Configure - Accounts - Setup for sending and receiving messages Confirm before send is unchecked Send messages in outbox folder "on all mail checks" Default send method "send now" Have to do the File > Send queued messages > via thing even afer several mail checks or it stays in the outbox
