Hi Rahul,
It is possibe to create a Mail Journaling database that will be able to capture all messages:
"Mail journaling enables administrators to capture a copy of specified messages that the Router processes by the IBM® Lotus® Domino®system. Journaling can capture all messages handled by the Router or only messages that meet specific defined criteria. When mail journaling is enabled, Domino examines messages as they pass through MAIL.BOX and saves copies of selected messages to a Domino Mail Journaling database (MAILJRN.NSF) for later retrieval and review. Mail journaling works in conjunction with mail rules, so that you create a journaling rule to specify the criteria for which messages to journal. For example, you can journal messages sent to or from specific people, groups, or domains. Before depositing messages in the Mail Journaling database, the Router encrypts them to ensure that only authorized persons can examine them. Journaling does not disrupt the normal routing of a message. After the Router copies a message to the Mail Journaling database, it continues to dispatch the message to its intended recipient. "
Please take a look at this Link:

Would that be something that you were looking for asking the question?
Kind regards,
