Hi,
I wonder if you have ever seen signed messages in knode appear like in kmail
with nice header.
ATM I see the signature as attachment and when try to open it throws gpg
error.
IMO the problem is in Module::prepareMessageForDecryption, but looking into
the code I doubt it was ever working

Opening the signature seems to be another issue -> perhaps threating
attachment or so via some part.

I just generated a key for deloptes@... and try sign this message and
it says I have not configured the key for signing.

thanks

regards
