Backup mail server
Is it possible and how to set up a backup mail server by sendmail or qmail, or ...?
When the original mail server is down, It should be able to recieve all emails sending to the original mail server, and auto forward (re-send) them after the original mail server is up again.
In DNS setting, I know that I need to configure it as
MX 10 original.mail.server
MX 20 backup.mail.server
