2016-06-02 10:15:33,437 WARN  [qtp509886383-1033601:https://63.237.45.232:443/zimbra/] [] webclient - system failure: error while proxying request to target server: HTTP/1.1 503 Service Unavailable
com.zimbra.common.service.ServiceException: system failure: error while proxying request to target server: HTTP/1.1 503 Service Unavailable

Solution

White-list the IPs or if impossible to white-list lots of IP address list then client can disable the DoS filter for the repeated login failure.

su - zimbra
zmprov mcf zimbraInvalidLoginFilterMaxFailedLogin 0

Then restart the mailbox services to reflect the changes :

zmmailboxdctl restart
