    Default Email clients unable to connect to Zimbra

    Suddenly, all our Email clients are not able to connect to our Zimbra Server. This includes Outlook, Zimbra Desktop and even our Canon Copier scan-to-email function.

    The web client is still functioning, but calendar appears to be freezing.

    We have restarted Zimbra services and even reboot our server. What could be the possible cause???

    o Certificate Problems?
    o The entries for the MTA Networks get lost. ( zimbraMtaMyNetworks )

    The problem was solved. It was actually caused by our firewall! :P
    But I still appreciate your helpful response!
