Hi, I'd like to configure this kind of funcionality. I have 1 postfix box, which should relay mails to 1 of 2 internal mail servers(192.168.1.1, 192.168.1.2). When 1 internal mail server crashes, new incoming mails should be automatically send to another internal mail server. I don't want to use MX lookup.
I tried this configuration: in transport file example.com :[192.168.1.1] .example.com :[192.168.1.2] but without success. Another attempt in main.cf I specified relayhost = [192.168.1.1] in transport file example.com :[192.168.1.2] again,no success. Could you please write me the right configuration of fallback without MX lookup? Many thanks, Vladislav
