    I am trying to configure eMail notifications. I have an SMTP server set up that does not require authentication. I have attached a screenshot of the error. My configuration for the driver is:

    Server=XX.XX.XX.XX
    RetryCount=1
    Port=25
    FromName=NOC
    FromAddr=<my email address>
    MailEncoding=utf8
    IsHTML=no

    How can I troubleshoot this?

      You may also try adding

      LocalHostName=localhost
      

      into the configuration - some smtp servers may require this.

      To troubleshoot - set debug level 6 for tags nc and ncd.smtp:

      debug nc 6
      debug ncd.smtp 6
      

      in server console.
      Then try to send a notification, server log should have some information.
      Since smtp is not encrypted, you can also use tcpdump/wireshark to see communication with smtp server.
