Andreas, I have been a kmail user for a long time and with this app if you sent an encrypted email to a user and then you want to read it from the sent mail folder you can do this and I think it's a logical thing as it's I that wrote the email and it's not important if I haven't the private key (obviously) of the recipient user. If you encrypt all the email that you send you are in the situation that you cannot read them anymore, but it's absurd as it's you that wrote them.
