Yes. All Didactum server room monitoring devices offer SMTP relay or mail relay server functionality.

That's correct. Email notifications and alerts are primarily stored in the system tree of the SNMP monitoring hardware. The settings in the menu "System Settings" => "SMTP" are for easily entering new email parameters. The settings entered there are then set by the system as the default. Please note that the email will be sent to the address(es) entered in the properties of the "Email" element in the system tree.

Please check the IP address and DNS entries in your Monitoring System 50 IP Thermometer. Without a valid IP address and DNS entries, the measurement and monitoring system cannot determine the address of the Google SMTP server (smtp.gmail.com). Please contact your network administrator for assistance.
