    Default ZCS-6.0.5 POP3 Connection Problem

    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.

    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)

    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?
