messages in sentbox

[tn fenster <balsa ars-solvendi de>]

Hello,

balsa (2.0.16) copies files into the sentbox even if I don't actually  
send them but just put them in the outbox via "send later". Is there a  
way to avoid that behaviour as it is very confusing if I decide later  
not to send the message and delete it from the outbox and still there  
is the message in the sentbox implying that I sent it...
