Message Delivery Is Slow between Domains

Explanation: Message delivery between GroupWise users in different domains is slower than desired.
Action: Review the stages of message flow between domains. See Message Delivery to a Different Domain in GroupWise 7 Troubleshooting 3: Message Flow and Directory Structure.
Action: If message delivery between users in the same post office is also slower than desired, see Message Delivery Is Slow in the Local Post Office. Resolve problems in local post offices first before troubleshooting problems between post offices or domains.
Action: If message delivery between users in different post offices in the same domain is also slower than desired, see Message Delivery Is Slow between Post Offices. Resolve problems between post offices before troubleshooting problems between domains.
Possible Cause: The MTA has been installed on a server with insufficient system resources.
Action: Check the utilization and memory on the server where the MTA is running to see if other programs are taking more resources than usual. If the MTA has fewer resources than usual, it can take longer to deliver messages between domains. Make sure the server still meets the system requirements for running the MTA. See Agent System Requirements in Installing GroupWise Agents in the GroupWise 7 Installation Guide.
Possible Cause: The MTA is not configured optimally.
Action: Go to the server where the MTA is running. Check the MTA agent console to see how busy the MTA is. If the MTA is very busy, it can take longer to deliver messages between domains. If the MTA needs to handle the current load on a permanent basis, see Optimizing the MTA in Message Transfer Agent in the GroupWise 7 Administration Guide.
Possible Cause: The network itself is busy.
Action: Check network traffic between the servers where the POA and MTA are running. Heavy network traffic can slow down the transfer of GroupWise messages between domains. Also check general network configuration, looking for slow links, congested hubs, and busy subnets that lie along the route GroupWise messages must take between domains.
Possible Cause: Links between domains are not configured optimally.
Action: Check the number of hops the message must travel between domains. You can view this information for a message in the mailbox of a user who has problems with slow message delivery. If messages are being routed through a large number of domains, use the Link Configuration Tool in ConsoleOne® to design a more efficient route for messages between domains. See Understanding Link Configuration in Domains in the GroupWise 7 Administration Guide.
