similar to: Dovecot HA/Resilience

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. Thanks, Kishore

Thank you all for the replies.... 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 data stores on a Network / Shared Storage (But definitely not local disk, its a mount point). I have been asked to create a HA/Resilience for

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.

Hi, But there is no "doveadm backup" option in dovecot 2.0.9 version. [root at production ~]# doveadm -backup doveadm: invalid option -- 'b' [root at production ~]# dovecot --version 2.0.9 Copy the contents by using "scp", will that work?

I tried this command also. It didn't work. It shows syntax again. Please see the supported commands in dovecot 2.0.9 version. This doesn't support replication also as per syntax, if i am not wrong. Please suggest me. [root at production ~]# doveadm backup -u kishore at test.org.com remote:vmail at production2.test.org.com usage: doveadm [-Dv] [-f <formatter>] <command>

Hi I am in the process/planning of moving from my existing dovecot imap/pop3 server to 2 new servers (for HA/Resilience). I will be implementing dovecot replication on new servers. Please find my current and new servers versions. My Current Production Server details: ======================== Linux OS - Red Hat Enterprise Linux Server release 6.5 (Santiago) Dovecot version - 2.0.9

Hi All, I need to migrate the complete data & setup/environment from an old dovecot environment to a new dovecot environment.

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.

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 NFS storage shared by both servers (as long as only one has the floating IP, you won?t have issue with the

I am using pop3/imap, see the below file. We can't verify any logs? This is working fine from last one year. as part of testing we just stopped the services for 20minutes and restarted the dovecot and postfix server using "service <dovecot/postfix> stop/start". No issues so far... I would like know, if the application is reading the emails from the server, do we have any log

Hi , I have tried the below command from the new server. But I am getting an error. Anything is missing here? ======== [root at production1 test.org.com]# doveadm backup -R -u kishore at test.org.com remote:vmail at production2.baplc.com vmail at production1.baplc.com's password: usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A]

I seem to recall a post a while back where, due to the age of the remote end, the remote side command had to be entered in the command executed on the local side.

Fair enough but the command snippet I posted was taken directly from your earlier post dated Mon Jul 27 23:11:06 EEST 2020 and it does say ?production1??I just double-checked as well... FWIW?the server order in the command you just pasted is the exact reverse from the Jul 27th post I mentioned above? Here you appear to be exec?ing the command on prod2 and trying to pull from the remote of prod

Hi Benny and Dovecot, Thanks for the reply. Actually my question is, is it possible to verify anything now whether the email has been pulled by application/server from the "Maildir/new" or "Maildir/cur" folder in my POP3 server? at present I am not using lmtp yet. When I configured the outlook to access the one of the email box in the server, I get the email. But do we have

Well that option set still doesn?t look correct? Here is the doveadm option set from my 2.2.2 server which is several weeks\months before 2.2.36?

Yes. Please find the details of the servers below. I am executing the command from one of the new servers.

Not sure if this matters but the prompt when attempting the ?doveadm backup? command shows it to be a ?production" server? [root at production1 <https://dovecot.org/mailman/listinfo/dovecot> test.org.com]# doveadm backup -R -u kishore at test.org.com <https://dovecot.org/mailman/listinfo/dovecot> remote:vmail at production2.baplc.com

Thank you for the reply. As per our current infrastructure, I can go maximum of the redhat 7.7 version. Not more than that. Am I able to install or upgrade to dovecot 2.3 version in redhat 7.7? I have another question. I understand redhat 6.10 will go out of support in november 2020. But this is a test environment. Am i able to install dovecot 2.3 version on redhat 6.10? For the Live support, I
