If you just want active/standby, you can simply use corosync/pacemaker as other
already suggest and don’t use Director.
I have a dovecot HA server that uses floating IP and pacemaker to managed it,
and it works quite well.
The only real hard part is having a HA storage.
You can simply use a
Yes, but it works for small systems if you set IP source address
persistence on LB or even better, if you set priority to be
Active/Standby. I couldn't find a good example with dovecot director and
backend on the same server, so adding another two machines seems
overkill for small setups.
If
Also you should probably use dovecot director to ensure same user sessions end
up on same server, as it's not supported to access same user on different
backends in this scenario.

Hello,
you need to "clone" the first server, change the ip address, mount the
same maildir storage and use some mechanism to share the accounts database.
Then you need to put a TCP load-balancer in front of the servers an you
are good to go. This is the easiest solution if you already have

I have the test environment with the same configuration. But I have been
asked to go with same environment for HA/Resilience in Live.
Yes, I have only one Live server. It is configured in "Maildir" format. The

You have only one server? Or is this running on virtualized environment

Thank you Aki for the reply.
But I cannot disturb the version at present as it is a live server and
thousands of emails will circulate every hour.
Could you please suggest me how to create HA/resilience
You can do it using replication,
https://wiki.dovecot.org/Replication
but since you have no staging/test environment, I would advice you to get one.

Could you please suggest me how to create HA/resilience for the existing
environment. I have another server ready with the similar configuration.
