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.
