Re: Backup mx server

It depends on your requirements.

If you just need a temporary backup mx server, then just Postfix (or any other MTA) should be fine, update MX DNS record of your mail domain and list it as a backup mx.

But if you want to verify whether recipient actually exists (on primary mx), then you need some kind of sql/ldap replication. It will help reject some spams, but as you can imagine, more softwares and maintenance work involved.
