Listening on primary and backup MX addresses
============================================
This week I was doing some expiriments: I configured Postfix to
make postscreen listen on both primary AND backup MX addresses.
This was a matter of adding a second IP address to the ethernet
interface of my mail server, then adding a backup DNS MX record
that resolves to that second IP address.
Does this solution also work when you use two different machines (One
for the primary MX and one for the backup MX)?
Or do i need 3 MX Records then? One for the primary (on machine one) one
for the backup (also on machine one but on another interface) and one
for the "real-"backup on a third machine?
Best regards
