I am a new user of newpki. I use the user guide to install it but I have a problem trying to sign an email with a certificate created with newpki. I have a root CA and a child CA tree. The child CA is to certificate mail certifications. When I create a certification for a user there is no problem but when I try to use it to certificate an email there is a problem with the mail CA. The root CA is valid and the user certificate is also valid. But the intermediate certificate is not valid. How can I solve this problem???
Thank you in advance
