I managed to install Corteza successfully, I used the older version and had to do a complete re-installation, lost some files in the process but no big deal.
I entered SMTP config as prescribed
This same config worked fine with the previous installation. I do not get any errors on the logs, in fact I get conformation that the email was sent, but there is no email in my inbox - it never arrives.
I tried different email addresses just to make sure, same problem.
