I want to build a second Kerio Server for backup/Failover (MX 20) and also host a few e-mails for the local network...
Senario,
I have 2 locations, Maryland and Alabama, Currently we only have a mail server in Maryland no redundency/failover. I want to instal a second server in Alabama as an MX20 for Maryland as well as a MX 10 for Alabama..

I want to host alabamas mail on the MX20 and have it work as a redundant server for maryland, and visa versa in Maryland


Can Kerio do this Out of the box?

I never set-up the second server for my network but I think it is possible without any major problem.

Nope, not in 6.x
There is some cluster support in 7.0, but it does not seems to be frontend cluster, only backend (connections to users) and storage will NOT be redundant, as I read the whitepaper.

I am looking for a solution to this as well. What about a simple solution for near-line fail over? Can you use Microsoft's DFS to replicate the store and other directories that are needed?

Then when you need to fail over, all you would need to do is bring the secondary server online, and maybe change its address.

Has anyone tried something like this?

It is possible to Virtualize your machine that runs Kerio Connect, then utilize the high availability features of the virtualization infrastructure. We currently use Parallels Server For Mac to provide a limited but very functional system for quick recovery from hardware failure and other failures. We have this system hosted at a colocation facility that has redundant power and data connections. Some of the higher end solutions available from VMware could allow for live migration of the Kerio Connect server to other physical locations.

I m running Kerio 6.x for a client in a near-redundant model (no access for users) when primary server fails, as secondary server does not have users configured. DNS points to to MXs, one with higher and second with lower priority and ETRN downloads are configured, so emails to our client's domains do not bounce back to senders even when their primary server is down and are queued to their secondary server and once primary is live again, it ETRN downloads from secondary servers queues.
I am also looking for a auto-fail-over cluster(high-availability and/or high-processing) solution for this client as well as other clients. Is it available in Kerio Connect 7? if yes how?
