Hi All,
I request your help on this.
I have 2 dovecot test servers (IMAP protocol) installed with the following
configuration.
============[root at devap01 ~]# cat /etc/redhat-*
Red Hat Enterprise Linux Server release 6.10 (Santiago)
[root at devap01 ~]# dovecot --version
2.0.9
[root at 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.
1. 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?
2. 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 at 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.
Thanks,
Kishore Potnuru

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.
