Cannot send emails through Outlook: reported error 0x800CCC0f, the connection to the server was interrupted

    I would like to point out to another possible cause for this error (0x800CCC0f). If you are trying to connect with multiple devices behind the same IP address, you can get the same behavior from Outlook and the very same error message. The solution is described here:

    Solution for error 0x800CCC0F in Outlook

    Basically, in this case, you need to modify your MAXPERIP parameter in postfix to prevent connection interrupts and restart the postfix service.
