Today I am not able to send emails out with windows live mail. I have done all the suggestions

mentioned in all the other post about this issue and nothing works for me. My email setting are

exactly as they should be via my email provider. I am using Mcafee and everything is the same as it always

has been. Please help!

An unknown error has occurred.
