Hi All,
I need your help on one of the issue in Dovecot.
Why do you send that request to me personally in Cc:?
I have the dovecot version 2.0.9 installed on RHEL linux 6.10 version. It's a single/standalone Live server.
Now I have created another server with the same configuration for the resilince purpose. I also tested and I am able to send the emails to both of the dovecot servers separately/individually. They are working fine.
Now I have added those two servers under a F5 load balancer and created a FQDN (example: testing.test.com). I changed the rules to send the traffic to FQDN "testing.test.com", where it should redirect the email to one of those 2 servers.
When I sent the email to FQDN "testing.test.com", I am getting the below error.
pf1_inbd/smtp[30292]: 66A5F5F6: to=xxxxx@yyy.com, relay=testing.test.com[xxx.xxx.xxx.xxx]:25, delay=13, delays=0.09/0.08/13/0, dsn=4.4.2, status=deferred (lost connection with testing.test.com [xxx.xxx.xxx.xxx] while receiving the initial server greeting)
That's the MTA on port 25 not reacting as it should. That's no dovecot iisue.
Could you please let me know how to fix this issue? It's a great help for me.
Thanks & Regards, Kishore Potnuru
