Dear Mauricio,

To resolve the authentication issue with your SMTP server using the CP 243 IT for sending emails, consider the following steps:

1. SMTP Configuration:

   • Ensure you're using the correct SMTP server address and port. For example, usesmtp.une.net.cowith port 587 for TLS.

2. Authentication:

   • Since the SMTP Wizard doesn’t allow password entry, you may need to look for a firmware update or documentation that enables authentication.

3. Alternative SMTP Relay:

   • If the device is limited to sending emails only within the same domain, consider using an external SMTP relay service. These services often allow you to send emails to different domains and support authentication.

4. Check Documentation:

   • Refer to the CP Web Server manual for specific instructions regarding SMTP settings and authentication. If needed, contacting Siemens support may provide additional insights.

5. Considerations for Sending to Other Domains:

   • If you need a VPS with port 25 open, check here this can help manage email sending requirements more flexibly. You can avail of this option from providers that support SMTP configurations.

If you need further assistance, feel free to reach out.

Kind Regards,
