2. The Router splits the incoming message into two parts: the header and the content. The header consists of the message's To, cc, bcc, Subject, and From fields. The content contains the body of the message, along with any file attachments.

Note If the combined size of a message and its attachments is 1KB or less, IBM® Lotus® Domino™ delivers the complete message to the recipient's mail file and does not use the object store.

4. When a recipient opens the message, the header activates a link to the message content, which is stored in the shared mail database. The message appears as though the entire message is stored in the recipient's mail file.

5. If the recipient deletes a shared message, Domino deletes only the header in the recipient's mail file. The content is not affected because it is stored in the shared mail database.

6. After all of the recipients delete the message header from their mail files, Domino automatically purges the obsolete message, including the content in the shared mail database.

• If a user edits and saves a received message, Domino stores the revised message in the user's mail file in its entirety and deletes links between the user's mail file and the message body in the shared mail database.
