SSH port change from 22 to XXXX [Zimbra]

-
After installing the Ubuntu Server, we have changed the default ssh port from 22 to XXXX for security purpose.

For that, while accessing the email queue or monitoring graphs and other services at times server (zimbra) gives the exception saying "Server error encountered" with the system failure exception during auth. mailbox.log would have similar exception.

com.zimbra.common.service.ServiceException: system failure: exception during auth {RemoteManager: mail.domain.com->zimbra@mail.domain.com:22}
ExceptionId:qtp1068934215-357:https:https ://mail.domain.com:7071/service/admin/soap/GetMailQueueRequest:
Code:service.FAILURE


Solution:

#su zimbra
$zmprov ms mail.example.com zimbraRemoteManagementPort XXXX


Now check the status again.
