- Failover Relay Server When you have your own mail server provided with a double network connection, or a backup mail server in a failover location, you may configure the SMTP failover option of the Protector.This feature allows to automatically switch to the alternate server (failover) if the connection to the main server should fail.
The function is available through menu SMTP > SMTP Configuration. Here you can define any number of servers to send clean mail to. If you want to create a failover connection for a mail server, create a new entry for an existing domain and leave the Master check box unchecked.
The new SMTP connection will become the secondary (failover) connection for that domain, whilst the existing one will become the master. To switch roles, edit one SMTP and click on Master to reverse its status.On the list, the Master connection is marked with the symbol , and the secondary (failover) connection with .
When the Protector is using a failover connection, it will revert to the master connection as soon as it becomes active again. The Protector can handle an unlimited number of failover connections for the same domain. Each connection must use a different IP address.
