I have a[n] similar issue which started a couple of days ago.  I cannot send emails, but have no problem receiving them.  My error message reads as follows:

smtp-server.roadrunner.com

WindowsLive Mail Error   0X80070057

Protocol SMTP

Port 587

Secure SSL: Yes

I called my email provider and they went all through my server settings.  I was told they are as they should be.  They advised me to get in touch with MS.  I spoke to a support person at MS who told me that since I have Windows 7, I had to go to support.live.com.    I hope you can help
