Add feature backup mx and DNS slave
I have a multiserver installation where two servers are configured as mail. first mx.domain.com second backup.domain.com It is possible to add a feature that would, in the case of multiple mail servers to appear in adding the email domain server selection which serves as a backup mx?
When choosing a backup mx would be created in the DNS MX record and the necessary settings for operation of the backup mail server?
The same would be good for DNS. The first server as the master and the other as the slave.
Creating all these steps are time consuming and easily forgets things.
