Access Mode: Client/Server

This message flow diagram illustrates how a GroupWise message travels from one user to another in the local post office when the client and POA communicate by way of TCP/IP.


Message flow with client/server access
Stage Icon Description

Stage 1
Sender

User icon

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

Stage 2
Sender's
GroupWise
Client

Client icon

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

Stage 3
POA for Local
Post Office

POA icon

The POA receives the message from the GroupWise client and 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.)

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 (msgnn.db) so the new message appears in the recipient's mailbox.
  • Updates the message in the message database (msgnn.db) with a Delivered status for each recipient.
