Ensure your email server supports SSL/TLS for secure communication. In the Reolink camera settings: Set the SMTP Server to your email server IP (192.168.10.106). Specify the SMTP port that your email server uses for SSL/TLS. Enter the username and password for authentication. Make sure the SSL/TLS option is enabled in the camera's email settings. Double-check your email server's firewall and access logs to see if the cameras are trying to connect and if there are any errors. Ensure there are no IP restrictions on the email server preventing the cameras from connecting. If these steps don't work, reaching out to Reolink support with specific details might be necessary, even if the issue isn't with your network. MyTHDHR Benefits
