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
