I have a question on how Sophos UTM 9 send its reports? I have been looking through the firewall to see if there is a setting for the SMTP server or does it magically talk back to Sophos HQ and send the reports https://nox.tips/? (those are under logging & reporting). Its for some reason stopped a few weeks before I started here.
Salut and welcome to the UTM Community!
If Amodin's suggestion doesn't resolve your issue, please give an example of a report that has stopped.
Cheers - Bob
