Hello, With ISPConfig 2 I could use a file and enter: .domain REJECT to block all subdomains from spammer domains. Now in ISPConfig 3 this is not working as expected. If I enter .domain in any global whitelist or blacklist, and then try: postmap -q subdomain.domain mysql:/etc/postfix/mysql-virtual_client.cf It doesn't work. But if I do: postmap -q .domain mysql:/etc/postfix/mysql-virtual_client.cf It works. I get an "OK", but clearly this is not what I'm expecting, since it is matching the exact mysql query, but if I use a subdomain, doesn't match anymore. Is this a bug? I want to enter a domain in global filters and automatically include all subdomains. How to do this? Thank you in advance.
