Stops the SMTP interface.
You can use this command to stop the SMTP interface from receiving SMTP traffic from an antispam device or MTA. The Email Security — Server appliance continues to analyze the emails it already received and continues to block them or deliver them to the downstream mail server until the queue is empty. New incoming emails are either queued in the upstream MTA or routed to another appliance, depending on your network deployment. You can monitor the queue, wait for it to clear, and then start the maintenance activity.
Note
The Email Security — Server Congestion Control feature has a "Refuse Connection" threshold. When the threshold is reached, the feature automatically stops the SMTP interface. The
Congestion Control in effect?field in the output of show email-analysis mta status shows whether the SMTP interface is already stopped for this reason. If the traffic falls below the threshold during the maintenance activity, the SMTP interface will automatically start again. To prevent this, use email-analysis mta smtp stop to manually stop the interface. (For information about the Congestion Control feature, see the Email Security — Server User Guide.)
