Exchange SMTP submission TCP port 587

128-exchange-smtp-submission.yaml

TCP

What this example does

Exchange infrastructure monitoring: Exchange SMTP submission TCP port 587. It helps operators check the availability of this client-access or mail-routing dependency.

Checks and behavior

  • Checks that a TCP connection can be established to the configured host and port; it does not prove protocol login or mail delivery.
  • Formats results for nagios output.

Adapt example domains, addresses, credentials and thresholds to your environment before use.
