That statement and the one above in red contradict each other.
The error code 0x800CCC79 indicates that you're not Authenticating against the Zimbra server, you have a configuration problem.
Under no circumstances (if you care about security) should you have Clear Text login enabled on a public service, anyone can sniff your connection and get username/password details.
