This error is often solved by making sure our outgoing authentication is setup properly.
In Outlook Express choose "Accounts..." from the "Tools" menu. On the "Mail" tab click once on your account to highlight it. Then click on the "Properties" button. In the properties window click on the "Servers" tab and make sure that the check box at the bottom which says "My server requires authentication" is checked. Then click the "Settings..." button. Make sure that the option "Use same settings as my incoming mail server" is the option that is marked. Click "OK", then click "OK", then click "Close". Now try sending your email again.
