Hi!
DRBD might be an alternative, http://www.drbd.org/, for the SOGo server,
database and mail store. And Postfix (check out the the install script from
iRedMail, http://www.iredmail.org/) as a backup MTA. I am exploring the
possibility to use virtualized SOGo server on KVM. The LV for the virtualized
server and the LV for SOGo database and mailstore will replicate to a backup
server. And the backup MTA, also virtualized, running on the backup server.

Hi,
I'm am looking at venturing into sogo as an exchange replacement, and have a
question before I begin. I promise I have searched before posting, but can't
find anything related (or I may have poor keyword choices :-) So I
apologize if
this has been discussed already.
We have a couple of office locations, and I'd like to set up 2 servers, 1 at
each location, that mirror each other. That way if one location goes down
(power or internet loss or hardware failure) the other server can still at
least receive SMTP. It would be great if the client side connectivity could
also work when one or the other servers go down, but not as important as
making
sure we don't miss any incoming mail over SMTP.
Is this possible?
Thanks in advance,
Carlin
You can take a look at HAproxy
Haproxy is a http and tcp proxy. We use haproxy to balance trafic between our
SOGo backend servers. With SMTP also you can balance using MX records from DNS,
but POP or IMAP is more complicated because you need distribute/replicate the
mail storage.
