Just some ideas about using something like heartbeat to load balance 2 
or more MTA servers. Say in the case you have 2 servers and wish to 
combine them in a load balancing set up. This would require a 3rd server 
to serve as a load balancer, either using heartbeat or a dedicated 
machine like a cisco box.

If this is the case wouldn't implementing a load balancing setup 
actually introduce more points of failure? You have halved the chance of 
a failed MTA server causing downtime, but introduced the chance of the 
load balancer failing, causing downtime of both MTA servers. You also 
may have to deal with the added complexity of replicating the mailstore 
on 2  (in this example) servers, and such a mechanism (using rsync, or 
drbd) will have its own chance of failure.

Or is there a way to access a server directly, automatically, when a 
load balancer fails? Maybe I am missing some obvious things.

Thank you,
Jeroen
