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?
Now I have added these 2 servers behind the Load Balancer. Enabled 110/143 ports on the Load Balancer FQDN (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". 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), 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.
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 = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb { args = uid=vmail gid=vmail home=/r3/mail/virtual/%d/%n driver = static } mail_debug = no verbose_ssl = no
Please help me here.

Kishore,
please don't address me personally. This is a mailing list and I don't offer / sell consulting.
Let me comment only on the versions you provide. Please be aware that RHEL 6 will get EOL by end of November this year. So your strategy better comprises a migration to RHEL 7 or RHEL 8.
Along that steps to a current RHEL major release you will profit from newer Dovecot and Postfix releases. Running RHEL 8 you would even get pretty current releases, still supported by the upstream projects.
Alexander
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 will be doing it on redhat 7.7 version.
For testing, I am trying redhat 6.10 version, if it is successful, i will be trying the Live one's on redhat 7.7 version.
Please help me if it is possible to install dovecot 2.3 on redhat 6.10? This is a temporary test setup only.
Thanks, Kishore Potnuru

Believe me, there is no technical reason why you can't use the current update release of RHEL 7. Current is
# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.8 (Maipo)
redhat-release-server-7.8-2.el7.x86_64

Red Hat does not provide a newer dovecot. If you don't need their support and just test out dovecot 2.3 you can get it as a working RPM package from ghettoforge.org.
For testing, I am trying redhat 6.10 version, if it is successful, i will be trying the Live one's on redhat 7.7 version.
Please help me if it is possible to install dovecot 2.3 on redhat 6.10? This is a temporary test setup only.

I am running Dovecot 2.2 "u" on CentOS from https://ius.io/. If there is a package there for 2.3, it should be possible to upgrade on either CentOS or RHEL.
I am still a little bit confused or concerned why mainstream packages seem to be lagging so far behind on CentOS and RHEL since the sudden acquisition or hostile corporate takeover of Red Hat by IBM.
Possibly a corporate labor-union work slowdown. IBM is too big, too blue, and too politically correct. Something is a little bit off. Too many echoes in the hallways.

Hi Aki,
Am I able to install (2.3 version) on RHEL 6.10 or RHEL 7.7 versions? Will there be any issues? I know RHEL 6.10 is out of support in November. But I want to understand and try in my test environment.
Is it possible?
thanks, Kishore

Why do you ask? If you open te repo link you can see there is 2.3-latest there not? Of course you will have issues installing these if you type as root cd / && rm -R -f * You say you are testing, so do the testing.

If you have artificial constraints that limit your software to only what is available for old Extended Support systems them when that old software is not working, you need to go to the people providing the extended support and have them fix the software.
I something is working in the current Dovecot but you can't use the current dovecot, there's not really any way for dovecot to solve that for you.
With the rapid changes in security requirements and in particular for mail, running mail on a 10 year-old release and maybe considering updating to a 6 year-old release is just not a good plan.
It seems to me that mail, DNS, http, and TLS/SSH/etc software should be kept up-to-date on any forward-facing machines. "Extended" versions of the OS sound like they're a great idea, but when they leave you behind with broken or vulnerable software is there really a benefit?

Then the OP should be able to update to a dovecot that doesn't have the issue, right?

I have no idea what his issue is, and why he is stuck even in specific releases. I have been running dovecot on el6 and el7 for years and years without issues.

https://repo.dovecot.org/ <https://repo.dovecot.org/> has 2.3.10.1 CE release for CentOS 6. It should work on RHEL 6 too.
But since support for CentOS/RHEL 6 is dropping soon, I think we will stop building CentOS 6 CE releases soon. Not sure what will be the last one as I'm not in charge of that.

Testing with version 6.10 and then running on 7.7 is probably not a good idea. I highly recommend the same versions of software for testing and production - so better start your tests on 7.7
