Mapped/UNC Link Open: Transfer between Post Offices Successful

This message flow diagram illustrates how a GroupWise message travels from one user to another between post offices in the same domain when the mapped or UNC link between the post office and the domain is open.

Message flow when the mapped or UNC link is open

Stage	Icon	Description
Sender		The user sends a message to recipients in a different post office in the same domain. In this diagram, the delivery mode setting for the local post office is Use App Thresholds and the threshold is not exceeded.
Sender's GroupWise Client		The GroupWise client performs the following actions for the sender: Adds the message to the message database (msgnn.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 the post_office\offiles\fd0-f6 subdirectory assigned to the sender 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.) Creates a copy of the message in the appropriate priority 0-7 subdirectory of the MTA input queue in the sender's post office. If client/server mode were in effect for the post office, these actions would be performed by the POA instead of the GroupWise client. See Access Mode: Client/Server.
MTA for Local Domain		For mapped and UNC links, the MTA scans its input queue in each post office for messages to process. You can control the rate at which the MTA scans its input queues. See "Adjusting MTA Polling of Input Queues in the Domain and Post Offices" in "Message Transfer Agent" in the GroupWise 6.5 Administration Guide. When it detects a new message, the MTA picks up the message from the sender's post office and transfers it to the MTA "in progress" (gwinprog) queue. From there the MTA transfers the message to the output queue in the recipient's post office. The MTA output queue is the input queue for the POA in the recipient's post office.
POA for Recipient's Post Office		The POA polls its input queue regularly. When it detects a new message, the POA for the recipient's post office performs the following actions: Adds the message to the message database (msgnn.db) corresponding to the one assigned to the sender. Creates a pointer in the recipient's user database (userxxx.db) so the new message appears in the recipient's mailbox and updates the notification information in the user database so the recipient can be notified of the message. Places attachments larger than 2 KB in the post_office\offiles\fd0-f6 subdirectory corresponding to the one assigned to the sender 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.) Creates a Delivered status message in the appropriate priority 0-7 subdirectory of the MTA input queue in the recipient's post office.
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 creates an Opened status message in the appropriate priority 0-7 subdirectory of the MTA input queue in the recipient's post office.
MTA for Local Domain		For mapped and UNC links, the MTA scans its input queue for messages to process. You can control the rate at which the MTA scans its input queues. See "Adjusting MTA Polling of Input Queues in the Domain and Post Offices" in "Message Transfer Agent" in the GroupWise 6.5 Administration Guide. When it detects the status message, the MTA picks it up from the recipient's post office and transfers it to the MTA "in progress" (gwinprog) queue. From there the MTA transfers the message to the output queue in the sender's post office. The MTA output queue is the input queue for the POA in the sender's post office.
POA for Sender's Post Office		The POA for the sender's post office updates the sender's message database (MSGnn.DB) with the Delivered status information (and possibly Opened as well if the recipient has opened the message).
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).
