Electronic message journaling
IBM originally released a journaling feature in Lotus Domino 6, during 2002. IBM's journaling feature allows for copying every email as it is processed by the mail server to either a local database at the mail server or a dedicated remote database. IBM's journaling feature uses a rule-based selection to determine whether an e-mail should or should not be journaled. If properties about the e-mail match pre-defined administrator rule settings the e-mail will be journaled.
