Configure postfix as a backup[secondary] mail server

Tried various possibilities to configure the secondary MX server to queue mails properly if primary MX fails. Today tried the secondary MX setup with below configuration and it worked out.....   In main.cf file,   relay_domains = $mydestination example.com smtpd_recipient_restrictions = permit_mynetworks check_relay_domains   Included the transport_maps too in main.cf file in which configured the domain smtp transport address: transport_maps = hash:/etc/postfix/transport   In /etc/postfix/transport file,   example.com smtp:mail.example.com     Concept:-   If primary mail server for the domain example.com will down then all the mails are backuped/queued in secondary/backup mail server[postfix] once the primary server will be ready then mails are delivered  from backup to primary server.
