You may need to stop and start, or restart a channel under the following circumstances:
|
|
If you experience a problem with an IMTA channel, you may need to stop the channel, resolve the problem, then start the channel again. |
|
|
If you reconfigure an attribute of a channel, you will need to restart the channel so that the reconfiguration takes effect. (Typically, when you reconfigure a channel attribute using the Admin Console, you are prompted to restart the channel.) |
You can stop, start, and restart the connectivity services channels individually. If you need to stop, start, or restart any of the IMTA channels, (for example, the firewall SMTP channel), you will actually need to stop, start, or restart the entire IMTA.
To minimize the time it takes to stop/start or restart the IMTA, try to plan these operations during a part of the day when mail traffic is light.
