SMTP E-mail not working?

Hi,

Has anyone facing troubles using SMTP e-mails?

I have everything configured the same way in several devices, and my SMTP is actually working on a Grinder, on my local software based demo, but on my Jigsaw it doesn't send any e-mails...

The Configurator version is 4.6.26.

I already rebooted the Jigsaw, but it still doesn't send any e-mails.

The network is configured correctly, and the remote access is also working. It just doesn't send any e-mails...

Best regards
