I Ha configured Sophos UTM SG series with the email protection, I have followed the steps in the tutorial but still spam emails are not blocked.
We have configured earlier a portforwarding rule in the utm for the internal email server inorder for the users outside the network to still use the email.
I have already reported this case to sophos support and they advise me to disable the portforwarding rule because it's making emails to go directly in the internal mail server without passing the email protection proxy.
We have already disabled the portforwarding rule of the internal email and enabled the email protection, the users outside the network cannot communicate to the internal email server that's why we enabled back the porforwarding rule.
