Hi all,

I'm want to make sure that every mail I send is encrypted, if possible. I don't want to think about it and decide for every mail actively if I have a public key for all recipients or not. Is it possible to tell kmail to encrypt all mails by default if the public key for all recipients exists and if not to fall back to signing the mail only?

Thanks!

I think you can by going to Configure KMail > Security > Composing and select "Always encrypt messages where possible".
