    The message could not be sent. The authentication setting might not be
    correct for your outgoing e-mail [SMTP] server. For help solving this
    problem, go to Help, search for "Troubleshoot Windows Mail", and read the
    "I'm having problems sending e-mail" section. If you need help determining
    the proper server settings, please contact your e-mail service provider.

    The rejected e-mail address was ''. Subject 'xxx', Account:
    'Sky', Server: '', Protocol: SMTP, Server Response: '530
    5.7.0 Must issue a STARTTLS command first. 4sm18045agc.32', Port: 25,
    Secure(SSL): No, Server Error: 530, Error Number: 0x800CCC78

  4. "Unknown error" is usually caused by interference from a non-
    compatible antivirus program. Which antivirus are you running?
    As a minimum, email scanning in the antivirus must be turned off,
    although that may not be sufficient to eliminate all bad effects.
    In a worst case scenario, your antivirus may need to be uninstalled.

    One thing you should try as a possible quick fix is to delete that
    corrupted mail account, restart Windows Mail, then recreate that

    If no improvement, consider upgrading to Windows Live Mail,
    because it is less prone to suffering bad effects from overly
    intrusive antivirus programs:

    Email scanning in any antivirus must be disabled, for reasons
    explained here:
