    Hi, I hope someone may be able to help.
    I have been setting up mobile broadband (02) and anti virus software
    (Mcafee) today on my laptop which is fine except for my email.
    I can receive emails with no problem but I am unable to send emails. This is
    the error message that I get:

    An unknown error has occurred. Subject 'test', Account: 'pop.ntlworld.com',
    Server: 'smtp.ntlworld.com', Protocol: SMTP, Server Response: '421
    aamtaout03-winn.ispmail.ntl.com connection refused from [82.132.136.199]',
    Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67

    I don't know whether it is something to do with the virus
    protection/firewall, something to do with the email settings (which I have
    checked) or maybe something to do with the mobile broadband or something
    else. I have tried sending email with temporarily switching off the email
    virus checker, etc but this didn't work either.
    I hope someone can help if possible. Hope I've given enough info.
    Thanks,
    Sarah

  3. "Unexpected" termination is usually caused by interference from an
    antivirus program. Which antivirus are you running?
    As a minimum, email scanning in the antivirus should 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.

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

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