I have signed trusted  certificates in both the sending and the receiving units, and although I can send digitally signed emails, I cannot enable the black padlock icon to send enrypted email. I have tried to creat all types of certificates in keychain access but have failed. I have created my own certificate authorities as well as requesting authorities from comodo. How can I enable the black padlock icon?
