I am using IPSconfig 3 on CentOS 7.2 I wan to stop postfix from sending emails to specific domains. In looking at the transport_maps setting in my main.cf I see this configuration: transport_maps = hash:/var/lib/mailman/data/transport-mailman, proxy:mysql:/etc/postfix/mysql-virtual_transports.cf Does that mean that the transport_maps are stored in a table in MariaDB? If so, how to a navigate through ISPconfig to edit the settings? TIA Dave
