we are new th SMG and are trying to make it scan all our mail traffic. But we are experiencing problems with mails that are not scanned at all.
We want to scan mails from foreign domains that are not incoming mails. The SMG says they are external. These mails don´t come from our domains and don´t go to our domains. We have not found a way that these mails are beeing filtered by any filter policy.
How can we scan these mails?
