SECURING
To send an S/MIME-encrypted message, the sender must have the recipient's Internet certificate in their Contacts, an HCL Domino® Directory, or LDAP directory. The sender must also have a cross-certificate issued for the recipient or for the certifier who issued the recipient's Internet certificate.
About this task
If a cross-certificate is issued for a recipient's Internet certificate, only messages to that recipient can be encrypted. If a cross-certificate is issued to the recipient's CA, users can send encrypted messages to all recipients who have certificates issued by that CA, if you have the recipients' Internet certificates. If the Internet certificate is stored in a Domino Directory in another domain or in an LDAP directory, the directory needs to be accessible using directory assistance.
Procedure
1. The recipient must send an S/MIME signed message to you.
2. When you open the signed message, HCL Notes® asks if you want to add a cross-certificate if you do not already have one issued for either the author or the CA who issued the certificate to the author. Complete these fields and then click Cross Certify.
