Stopping Internal Mail Flow

The same procedure for stopping Internet mail flow applies to stopping internal mail flow. Set the Connection time on the Delivery Options tab of the connector to Never run.

Although the procedure itself is straightforward, you must give careful thought to the order in which you stop mail flow. Presumably, you will be stopping the mail flow to clean and disinfect the Exchange computers. It is critical that you develop an order of operations for taking the servers offline, cleaning and disinfecting them, and bringing them back online in such a way that isolates them from the risk of being reinfected. This plan is dependant on the topology of your Exchange routing groups and mail flow through other connectors, such as x400 and SMTP connectors.
