Hi All,
Can you please help me in understanding this:
- At present my RHEL server is 6.10 version. Am I able to install dovecot 2.2 or 2.3 version?
- Am i able to upgrade directly from 2.0 to 2.3? or I should go periodically from 2.0 to 2.1, then 2.1 to 2.2, then 2.2 to 2.3....?
- could you please suggest to me steps to pick the correct package to upgrade in the above version (2.1, 2.2, 2.3)?
- From Which location do I need to download the packages?
- I am using redhat servers. Am i able to directly download and upgrade the software from my redhat linux server? Please advise step-by-step instructions for this?
Thanks, Kishore Potnuru

Hi All,
I request your help on this.
I have 2 dovecot test servers (IMAP protocol) installed with the following configuration.
[root@devap01 ~]# cat /etc/redhat-* Red Hat Enterprise Linux Server release 6.10 (Santiago)
[root@devap01 ~]# dovecot --version 2.0.9
[root@devap01 ~]# postconf | grep mail_version mail_version = 2.6.6
I have another server also "devap02" with the same configuration.
Couple of points/questions/queries here.
- I know these servers are having old dovecot versions. I would like to upgrade to the latest versions. Could you please suggest the steps for upgrading to the latest version in redhat (step by step details are helpful please) . If I upgrade to the latest version, will there be any impact on the existing configuration/setup?
Check the documents posted here:
https://doc.dovecot.org/installation_guide/upgrading/from-2.0-to-2.1/
https://doc.dovecot.org/installation_guide/upgrading/from-2.1-to-2.2/
https://doc.dovecot.org/installation_guide/upgrading/from-2.2-to-2.3/
Depending on your setup, you may also need to check for changes to additional software (e.g. amavis)
Now I have added these 2 servers behind the Load Balancer. Enabled 110/143 ports on the Load Balancer FQDN (test.pop3.testing.com http://test.pop3.testing.com) and opened the firewall ports. Here I configured IMAP settings from microsoft outlook to see the emails. I gave the Incoming Mail Server & Outgoing mail server as "test.pop3.testing.com http://test.pop3.testing.com". It is configured without errors in Outlook. But I see these 2 types issues (shared storage & individual storage)
a) individual separate storage - When I send 10 emails to LB FQDN (test.pop3.testing.com http://test.pop3.testing.com), the emails are going to 2 backend servers. But when i see the emails from Outlook inbox, it shows 5 emails from one server for some time. After sometime it shows other 5 emails in the inbox. But, I am not able to see all 10 emails at same time in my inbox. Please suggest how to fix this issue? In this scenario, I have separate individual storage in both the
servers.
I'm not sure if you've set it up already because it's unclear from the configuration you posted but, you may wanna have a look at: https://wiki.dovecot.org/Replication
I suggest using replication after you've upgraded since earlier versions of dovecot had a few issues.
b) common shared storage - I have tried a different scenario also. I also have one common NFS storage. So, I have configured that storage in both the servers. So when I sent 10 emails, I see all the 10 emails from both the servers as it is common shared storage. But, I am not getting those 10 emails delivered into my Outlook. I have made all the configuration correctly. Please suggest what is the mistake here.
Dovecot.conf
[root@devap01 ~]# cat /etc/dovecot/dovecot.conf disable_plaintext_auth = no
listen = * log_path = /var/log/dovecot.log mail_location = maildir:/r3/mail/virtual/%d/%n/Maildir/ passdb { args = /etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 ssl = yes ssl_cert =
userdb { args = uid=vmail gid=vmail home=/r3/mail/virtual/%d/%n driver = static } mail_debug = no verbose_ssl = no
Please help me here.
