Sorry to disabuse you twice in one week, but Murder is not designed to 
be fully redundant.  It's designed to support horizontal scaling; 
spreading mailboxes across multiple back-end servers.  Redundancy has no 
part in the scheme.  So even if one has 10 front-end proxies, and 10 
back-end servers, each mailbox has only one copy, living on one back-end.

I can attest to the quality of the replication solution, as I used it 
successfully in a medium sized deployment.  But when trying to stack 
replication on top of murder (or vice-versa), ran into many issues.  
This was all several years ago, and I do not mean to impune Cyrus 
quality.  Rather that each solution brings some degree of complexity 
with, and they don't necessarily mesh well together.

But my point here is simply clear things up.  Murder = Horizontal 
Scaling; Replication = Redundancy.
