Journaling e-mail messages, containing information about an e-mail message and/or entities associated with the e-mail messages, are sent to journaling mailboxes. An e-mail server sends an original journaling e-mail message, preferably through an envelope protocol extension, to an entity's journaling mailbox. Upon detecting additional recipients of the e-mail message (e.g. an expansion of a distribution list or alternate recipient forwarding rule) the e-mail server sends an additional journaling e-mail message, containing information about the additional recipients, to the entity's journaling mailbox.
