The clue is in the error message:

"Server Response: 555 Refused (external Mail From address). Please enable SMTP authentication to send mail"

Go into account settings and set the smtp server to authenticate.

 

For your future info:

 

Windows Live Mail is not part of Windows. (Yes I know this forum name is confusing!)

Right-click on the account name in the folder pane and select Properties. On the Servers and Advanced tabs, change your settings to match the ones given on this page. After checking them all, close down Windows Live Mail and wait a few minutes before relaunching and testing.

Settings are laid down by your Email Service Provider, so they are the ones to ask. Most large ESPs (like Virgin) have detailed instructions on their websites.


Windows Live Mail has its own support forums at the Windows Live Solution Center. Please direct any further questions you may have to one of the forums on the right-hand side of this page. You will probably be asked to give your versions of WLMail and Windows so that the answer can be more precise. To find your program version, in WLMail press Alt-H A. If this doesn't show you the version and build number, press Escape twice, then Alt-F B.
