Hi,

I would like to know if KC7 supports mirroring for DR purpose.

We want to have 2 servers with replicated DB (mailstore, accounts, etc), hosted on 2 different ISP lines.

One can be master, second is slave taking over when master is down (in case of HW issue or internet down)

Both servers should be able to receive mail (both will be configured via MX records in DNS)
e.g.
serverA mx 10
serverB mx 15

ServerA receives incoming mail by default (as it has higher MX priority) and replicates it to ServerB.
If serverA is down/inaccessible, serverB will receive the mail as a secondary MX and replicate it to ServerA once it is back online.

At the same time, if ServerA is down, ServerB should be able to take over the master role.

We will have a special script to check online status and server health and modify DNS records respectively in event of failure.

E.g.
all clients will use the same name in client config: master=ServerA
in case of failure DNS will be automatically changed to
master=ServerB
once ServerA is back online, DNS will change back.

Please advise what from the above can be achieved with KC7?
Main goal: have online DR environment that does not require any manual actions to switch from one server to another. Both servers should have the same replicated data

Target enviouronment: Linux

Tnx

Capability as you describe is not native to Kerio Connect. You'll be best served setting this up in a VMWare or similar environment.

Can somebody at Kerio please make a sticky topic regarding disaster recovery / replication? It seems to be a pretty common new thread topic.

Thanks,
lets simplify it significantly.

Is there any option to setup KC7 as an SMTP relay for specific domains in order to use separate instance as s secondary MX server.
(Accept incoming mails and transfer it to primary server when it is back online)

However, I guess that using standard Sendmail package for this will be a much cheaper anyway Smile

That, I think you could do, though I've never tried it.

Given ServerA is set up to host DomainA and ServerB is set up to host DomainB:

Set up DomainA on ServerB, but don't add any users to the domain. In the settings for DomainA/ServerB, on the "Forwarding" tab, check the option "if recipient was not found in this domain, forward the message to another host". Schedule it for off-line delivery (ETRN). Then on ServerA, configure an ETRN download of DomainA.
