Hi Dovecot team, I need help in configuring HA/resilence for my dovecot (POP3/IMAP) server. I have one RHEL Linux POP3/IMAP server with Dovecot version 2.2.10. I also installed the postfix(version: 2.6.6) in it. At present it have around 10 domains and each domain is having around 20 email boxes. It has very simple configuration. User's reading the email via some internal applications/Outlook. I would like to create resilience/HA for this environment. Could you please suggest me, what is the easiest way to achieve this? If any one can suggest step by step that will be more helpful to me. Thanks, Kishore -------------- next part -------------- An HTML attachment was scrubbed...

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 have only one server? Or is this running on virtualized environment with shared storage etc? It is quite difficult giving advice with such little knowledge of the environment. I am trying to migrate a running server to a new one with different configuration and mailbox format for storage, without any downtime. Prefferably one user at a time. It is not as trivial as I expected. -----Original Message----- To: dovecot at dovecot.org Cc: Kishore Potnuru Subject: Dovecot HA/Resilience Hi Dovecot team, I need help in configuring HA/resilence for my dovecot (POP3/IMAP) server.
