I have a client with an exchange server that need spam/virus filtering. How do I configure a domain to be accepted and filtered without having to add each user from their domain in the system? Are "Email Routing" domains filtered by amavis? Thanks! CT
Yes. Add an email routing and then add the domain to relay recipients. There is an issue in that function in latest ISPConfig though, you can find the solution here: https://git.ispconfig.org/ispconfig/ispconfig3/issues/4924
