Sometimes, a check option is all the difference.
Took a second try to get Live mail working correctly, here's the settings:
Incoming mail (POP3): pop-server.domain*.rr.com
Outgoing mail (SMTP): smtp-server.domain*.rr.com
Clear text autherntication
Does NOT require SSL
And of course your email - user ID - & password
*NOTE: were domain is replace with your roadrunner domain. For example mine is twcny, it is part of your e-mail.
Hope this is usefull to others.
