A week ago my Postfix server goes down because of error disks...I have to
review
the disks and finally restore a backup....I spent one dady and people from my
company had not mail service and they were not happy :)
I need a high availability system that let me have a second mail server online
INMEDIATELY the first mail server fails.
So, Linux HA Heartbeat is my solution, as Kevin told to me.

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.
