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 for the existing environment. I have another server ready with the similar configuration. Please provide any steps/link for me to proceed on this? It will be a great help to me.

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.

Newest version available on el7 is 2.2.36. You should be having no problems with updating minor versions. Or clone the production environment to a test environment and test the upgrade. -----Original Message----- From: Kishore Potnuru [mailto:kishore.reachme at gmail.com] Sent: 09 January 2020 17:45 To: Aki Tuomi Cc: dovecot at dovecot.org Subject: Re: Dovecot HA/Resilience Thank you Aki for the reply.
