-`MYSQL_ENV_MYSQL_USER` - The database username for Roundcube; defaults to `root`
+`ROUNDCUBEMAIL_DB_HOST` - Host (or Docker instance) name of the database service; defaults to `mysql` or `postgres` depending on linked containers.
 
-`MYSQL_ENV_MYSQL_PASSWORD` - The password for the database connection or
-`MYSQL_ENV_MYSQL_ROOT_PASSWORD` - if the database username is `root`
+`ROUNDCUBEMAIL_DB_USER` - The database username for Roundcube; defaults to `root` on `mysql`
 
-`MYSQL_ENV_MYSQL_DATABASE` - The database name for Roundcube to use; defaults to `roundcubemail`
+`ROUNDCUBEMAIL_DB_PASSWORD` - The password for the database connection
+
+`ROUNDCUBEMAIL_DB_NAME` - The database name for Roundcube to use; defaults to `roundcubemail`
