Directory catalogs and Notes mail encryption

When Notes® users send encrypted mail to users registered in secondary Domino® Directories, servers can use an extended directory catalog to look up the public keys of the recipients to encrypt the mail. Even off-line Notes users with condensed directory catalogs can flag mail for encryption; then when they reconnect to the network to send the mail, the clients look up the public keys in the extended directory catalog.

About this task

Storing public keys in a condensed directory catalog is not recommended because it greatly increases its size. Instead, set up directory assistance for the aggregated Domino Directories so servers can look up the public keys in them.

Servers do not have to trust a directory catalog or a Domino Directory for credentials to use the directory to look up public keys for mail encryption.
