Re: Qmail migration

Thanks to every body for valuable suggestions. I am working to have  
actual migration in next few days.
Another question. I want to install 2 or 3 qmail servers in a load  
balancing and active failover model.
Can any body help suggest the design from your experience....... thanks....
