Hello, I was looking for change my RBL settings and notices that if I put them inside ServerConfig->Mail it did not get updated. Running server.sh manually and adding some prints inside, I got to see that: $mail_config['realtime_blackhole_list'] is always equal to $old_ini_data['mail']['realtime_blackhole_list'] This is a Bug? Or someone can help me to get understand what happend? EDIT: forgot to say, Debian9 and ISPConfig 3.1.13 Thank you Regards
