I’m looking to set-up a primary and secondary mail server using 10.3 server. Does anyone know the best practice method for this?
Details
1. I’d utilising the virtual mapping in postfix for multiple domains.
2. Both servers would be connected through there own DSL connection(different providers) with static IPs each.
3. They would reside in the same room so using firewire as a TCP/IP connection between them would be possible.
4. MX1 would point to the primary mail server, MX2 would point to the secondary mail serverIf the Primary mail server was to go down all mail should be sent to the Secondary mail server. When the Primary comes back on line the Secondary mail server sends the mail to the Primary mail server….
Interested in knowing what the best scenario is?
Thanks for the reply. It looks to be alot easier then I was expecting. I will relay my success here when I’ve managed to get it up and running.
I also found this site that seems to cover what you are talking about

I have a similar but different plan to implement. I would like to act as a backup email for several domains (all on the same IP listed in my Server Admin GUI “Accept SMTP relays… list”) but none of the users are listed on my server, only on the primary MX. I’ve researched this and it looks like the Postfix permit_mx_backup command does this sort of thing, but I’m too much of a novice to know where to put this on the main.cf file. I’ve tried adding it to my “smtpd_recipient_restrictions = ” but that broke the smtp server upon restart. Do I need to define which domains the secondary (my) mail server should hold and forward, once the primary goes back online?
