When I am at home in my own network everything works correctly however when I'm away at either a convention or visiting someone outside my network I can receive my mail but cannot send from WLM.  I have tried to create new rules in my firewall for outgoing Windows Live Mail traffic but nothing seems to help.  The messages just sit in the OUTBOX. However at home this does not happen. I can go directly to my webmail account and send and received but WLM will not send.   Any suggestions?
