Description

Sender

The user sends a message to recipients in the same post office. The access mode setting for the post office is Client/Server Only.

Sender’s GroupWise Client

The GroupWise client communicates with the POA by way of TCP/IP.

POA for Local Post Office

The POA receives the message from the GroupWise client and performs the following actions for the sender:

  • Adds the message to the message database (msgnnn.db) assigned to the sender.

  • Creates a pointer in the sender’s user database (userxxx.db) so the message appears in the sender’s mailbox as a sent item.

  • Places attachments larger than 2 KB in one of the post_office\offiles\fd0-F6 subdirectories and creates pointers from the message to its attachments. (For database efficiency, messages and distribution lists larger than 2 KB are also handled as attachments.)

The POA also performs the following actions for the recipient:

  • Creates a pointer in each recipient’s user database (userxxx.db) to the message in the message database (msgnnn.db) so the new message appears in the recipient’s mailbox.

  • Updates the message in the message database (msgnnn.db) with a Delivered status for each recipient.

POA for Local Post Office

The POA communicates to the GroupWise client by way of TCP/IP that a new message has arrived.

Recipient’s GroupWise Client

The Notify component of the recipient’s GroupWise client notifies the recipient that a new message has arrived.

Recipient

Each recipient opens the message in the GroupWise client.

Recipient’s GroupWise Client

Each recipient’s GroupWise client communicates the Opened status to the POA by way of TCP/IP.

POA for Local Post Office

The POA receives the Opened status from the GroupWise client and updates the message in the message database with the Opened status for each recipient who opens the message.

POA for Local Post Office

The POA communicate the Opened status to the sender’s GroupWise client by way of TCP/IP.

Sender

When the sender checks the sent items in his or her mailbox in the GroupWise client, the message displays a status of Delivered for each recipient (and possibly Opened as well if the recipient has opened the message).
