@SteveMann The TP-Link community forum discussion that you referred to talks about users' experiences with the Omada software, particularly with regard to SMTP settings and the ability to send out automated email warnings in response to network events. But there is no explicit mention of SMTPget or similar terminology in the exchange. According to posts on other TP-Link forums, SMTP problems typically center on configuring the right port and SMTP server, as well as making sure the Omada controller has the necessary login information, such as a username and password.

Make sure you're using the email provider's legitimate SMTP settings and that no firewall or network settings are preventing email flow if you're troubleshooting SMTP problems or a related issue. For further information on potential issues, you might also look over the controller's event log.
