imap proxy configration

[Rama]

Hi,
We have installed Zimbra 8.8.8_GA_2009.RHEL7_64_20180322150747 with multi server architecture. Everything went fine except imap proxy configuration. We ensured the mailbox instance listening on proxy backend port, 7143 and able to telnet from proxy nodes which is listening on 143 for proxy requests for imap .

The issue is when proxy nodes making configurations it is creating a proxy config file with listening port 143 instead of 7143. Hence, proxy serves are failing to redirect imap connections running on mailbox server with 7143.
