Security grant hints

Pay attention at your access on mysql server.

We can consider three accessing level.

• First level is the super root access to the mysql server. You couldn't know these credential, you could ask at your sysadmin. With this access you can create the databases contained in db.sql.

• Second level is the RBL Manager access. This user can write, modify and read any table created at the above step. You can set this access running grant.sql.

• Third level is other client read-only access, like Postfix access, where needed. In this case you can define a user with read only access running client_grant.sql.

Repeat these checks for each database you add.
