I have a question about "roles", because the situations seems strange to me...

Why does a DNS server need a MySQL and or mail server installed on it? (and MySQL server needs a mail server) ?

For example, PowerDNS requires MySQL, so the MySQL package will be installed on the node with a "name server" role (the same for Mail server).

Thank you. Completely understand.
