When a location becomes closed (unavailable), the MTA waits before attempting to recontact that location. If the MTA waits only a short period of time, the MTA can waste time and create network traffic by trying to reestablish a connection with a closed location. On the other hand, you do not want the MTA to ignore an available location by waiting too long.
By default, the MTA waits 600 seconds (10 minutes) between its attempts to contact a closed location. You can adjust the time interval the MTA waits to meet the needs of your GroupWise system.
In the GroupWise Admin console, browse to and click the MTA.
Click the Agent Settings tab.
Decrease the number of seconds in the Attach Retry field if you want the MTA to try to contact closed locations more often.
or
Increase the number of seconds in the Attach Retry field if you want the MTA to try to contact closed locations less often.
Click Save, then click Close to return to the main Admin console window.
For a TCP/IP link, a location is considered open if the MTA receives a response from the receiving agent within the currently configured wait intervals. See Section 25.1.2, Adjusting the MTA Wait Intervals for Slow TCP/IP Connections. Otherwise, the location is considered closed.
For a mapped or UNC link, a location is considered open if the MTA can perform the following actions:
Create a temporary folder in the MTA input queue (domain\wpcsin and post_office\wpcsin folders)
Create a temporary file in that new folder
Delete the temporary file
Delete the temporary folder
