Setting up Notes® clients for S/MIME

Setting up Notes® clients to send encrypted messages

Notes® clients need the following to send encrypted messages:

• The recipient's Internet certificate stored in Contacts, the Domino®, Directory, or LDAP directory. 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.
• A cross-certificate issued for either the recipient or the CA that issued the recipient's Internet certificate. This cross-certificate must be stored in the client's Contacts.
  Note: It is not necessary to have the cross-certificate prior to sending S/MIME encrypted mail. Users will be prompted to generate the cross-certificate when they try to send the message.

Setting up Notes® clients to decrypt encrypted messages and send signed messages

To decrypt sent messages and send signed messages, Notes® clients need an Internet certificate stored in the Notes® ID file.

Setting up Notes® clients to verify signed messages

To verify the signature on a signed message, Notes® clients need a cross-certificate issued for either the sender of the message or the CA that issued the sender's Internet certificate. This cross-certificate must be stored in the client's Contacts.
