Dear, I want to have two Postfix SMTP servers, one active and one

Why do you want that ?
SMTP has built-in redundancy - just run multiple MX machines.
If you want instant IP-level failover, use a frontend loadbalancer
with heartbeat detection, but that's really not postfix-related.

Multiple MX machines doesn't suit to me because I need configurattion
and accounts replication for high availability.
Instead of replicating accounts, it would make more sense to use a
central account database such as sql or ldap to hold that information.
You can cluster those, too.
I use a secondary MX in order to storage messages when the main MX
goes down.
Any MX can do that :)
Seriously, do you have many issues with postfix not being available ?
If this was for georedundancy, or in areas where your internet
connection is not dependable, that makes more sense, but just postfix
doesn't die that easily.
