    This page says outgoing mail needs to be authenticated. Follow the instruction on the page and it should work.

    Give the service provider a call. If the incoming is working then the details should be correct.

    99.9% of the time you get this message it is the ISP at fault.

    If you know you have not changed any settings or passwords just leave it alone and give it time.

    Go back and try again after 30mins and if it is still the same look on the ISP home page and look at their service reports to see if the servers are down.

    You can always retrieve you mail through the ISP homepage if all else fails.

    Don't be tempted to change any settings or passwords as when it fails again and again, it makes you think that YOU have made the error!!

    Enjoy life, it's the only one you've got!!
