Hi,

I am seeking for a solution for having several SMTP/POP servers on 
different network locations, the problem is the following, we actually have 
one SMTP/POP server with MX backup to another server, ok this solution is 
ok for some scenarios but when the main SMTP/POP server goes down (it does 
not happen to much fortunately) the email is not lost but no one can access 
they email, and this tends to annoy people, is there any possibilty of 
having some kind of mirrored file system over the network so when one of 
the servers goes down the DNS would point them to the other IP (using the 
round robin dns feature or whatever) and people could download email?.

I have read about file system mirroring over NFS but it looks like 
something in development than a mature solution.

Thanks.
