I could solve that already, I was able to import my keypair, and to  
test the pubkey of a friend.

Now I get an error message when want to send a signed and encrypted email:

PGP-Fehler: Öffentlicher Schlüssel für l at l konnte nicht gelesen werden.

l at l is not the email address I entered in the TO field.

Is this an already known behaviour?
