Process 8: Async Gateway Delivers Message
The Async Gateway delivers the message to the remote GroupWise user.
Message Flow from Async Gateway to Async Gateway
Stage 1: Sender
The user sends a message to recipients in a post office in a different domain. In this diagram, the
delivery mode in the local post office is Use App Thresholds and the threshold is not exceeded.
Stage 2: Sender's GroupWise Client
The GroupWise client performs the following actions for the sender:
Š Adds the message to the message database (msg 0-24 .db file) assigned to the sender.
Š Creates a pointer in the sender’s user database (user xxx .db file) so the message appears in the
sender’s Out Box.
Š Places attachments larger than 2 KB in the post office\offiles\fd 0-7f subdirectory assigned to
the sender and creates pointers from the message to its attachments. (For database efficiency,
messages and recipient lists larger than 2 KB are also handled as attachments.)
Š Creates a copy of the message in the appropriate priority 0-7 subdirectory of the sender’s
MTA input queue.
If a different delivery mode were in effect in the post office, some or all of these actions would be
performed by the POA instead of the GroupWise client.
Stage 3: MTA in Sender's Domain
The MTA in the sender’s domain polls its input queue as specified by Scan Cycle in Agent Settings
in ConsoleOne
®
. When it detects a new message, the MTA recognizes that it must be sent through
a gateway and places the message in its output queue in the gateway’s directory structure:
