Hi All,
I need your help on one of the issue in Dovecot.
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)
Could you please let me know how to fix this issue? It's a great help for me.
Thanks & Regards, Kishore Potnuru
