For information on selecting MIME format for sent mail, see the topic Mail encryption.

Setting up Notes clients to send encrypted messages

Lotus Notes clients need the following to send encrypted messages:

• The recipient's Internet certificate stored in Contacts, the IBM® Lotus® Domino™, Directory, or LDAP directory. If the Internet certificate is stored in a Lotus 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 Personal Address Book.

  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, Lotus Notes clients need an Internet certificate stored in the Lotus Notes ID file.

For information on creating Internet certificates for Lotus Notes clients, see Creating Internet certificates for Notes S/MIME clients.

Setting up Notes clients to verify signed messages

To verify the signature on a signed message, Lotus 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 Personal Address Book.

For information on creating cross-certificates, see Creating an Internet cross-certificate for a CA.
