Are there any High Availability Solution for Postfix SMTP Server meaning
primary and secondary nodes in Active/Active or Active/Passive Clustering

Please describe the problem you're trying to solve instead of what you
perceive as the solution.
I will try to describe his problem:
- Postfix server crashes in flame = problem.
- Any (semi)-automated fallback server solution?
Hence the "High Availability Solution" question...
Well, there's the obvious one, which I use: Simply run Postfix on top
of a high availability virtual machine stack.
In my case:
- replicated disks using drbd
- Xen virtual machines
- crm for failover management
All the data is mirrored across two machines. If either a VM or an
entire machine crashes, the VM simply restarts on the other node. If you
wanted, you could set up Postfix as a managed resource, so that if only
the postfix processes die, it gets restarted.
You could probably use drbd and crm to mirror data and failover postfix
w/o a VM in the middle.
Take a look at http://www.linux-ha.org/wiki/Main_Page as a starting point.
