SMTP service monitoring

The Citrix ADC appliance has a built-in monitor that can be used to monitor SMTP services: the SMTP monitor. It periodically checks the SMTP service to which it is bound by opening a connection with it and conducting a series of handshakes to ensure that the server is operating correctly. If the SMTP service completes the handshakes properly, the monitor marks the service UP. Else, if the SMTP service does not respond, or responds incorrectly, it marks the service DOWN.

Note: Monitor probes originate from the NSIP address.

Parameter Specifies
scriptName The path and name of the script to run.
dispatcherIP The IP Address of the dispatcher to which the probe is sent.
dispatcherPort The port of the dispatcher to which the probe is sent.

To configure the built-in SMTP monitor, see Configuring Monitors in a Load Balancing Setup.
