Email Notification fails to send out??

[vinstaruser 0]

I got NVR device that comes with email notification feature which will help to notify the owner upon failure of IP camera.

However, I tried to configure with its settings based on mail server name, mail port:25 and its email sender address and could not receive on my side.

 

Usually, NVR could send out its notification to designated mail address. My IP cameras and NVR are connected in VLAN configuration which its VLAN ID are untagged in the network switch.

 

Was it due the VLAN setup though my IP cameras are functioning with its NVR?
