ZCS-6.0.5 POP3 Connection Problem

[sandiphw]

I have recently installed zcs6.0 on CentOS5.4 and it is in production. But I am not able to connect any account from thunderbird/ Outlook client through POP3.In global setting I have enabled POP3 and also enable the clear text log-in but could not success. I have authenticate my domain from an external ldap directory. All works fine for IMAP but for POP3 it even did not ask for password prompt. Which configuration I left behind?

Any help will be highly appreciated.

Can anyone give me any idea?

Are you trying to connect from a local subnet or is there a firewall behind?
Have you checked the COS preferences related to the POP3 Service ? There is flag that needs to be enabled)

I am trying to connect from lan. In COS also POP3 related all checkboxes are enabled.

But telnetting on the 110 port gives you any connection to the POP3 daemon listening ?

Yes, I can telent port 110 but when try to login it shows error: "Cleartext login disabled".

I have checked the followings from zimbra admin console:

1. In Global setting cleartext login is enabled
2. All maibox servers cleartext login is enabled
3. All COS, POP3 login option is selected.

Also from zmprov gacf, I have founfd that zimbraPop3BindOnStartup: TRUE
zimbraPop3BindPort: 7110
zimbraPop3CleartextLoginEnabled: TRUE
zimbraPop3ExposeVersionOnBanner: FALSE
zimbraPop3NumThreads: 100
zimbraPop3ProxyBindPort: 110
zimbraPop3SSLBindOnStartup: TRUE
zimbraPop3SSLBindPort: 7995
zimbraPop3SSLProxyBindPort: 995
zimbraPop3SSLServerEnabled: FALSE
zimbraPop3SaslGssapiEnabled: FALSE
zimbraPop3ServerEnabled: TRUE

I have not enabled SSL for POP3 anywhere.

What I am missing?
