how to get my "lifetime" email address to display to recipient

Hello, I switched from Outlook Express to Windows Live Mail with this new computer. I have not been able to figure out how to get sent mail to display my lifetime e-mail address (@pobox.com) next to my name. My display name looks like Firstname Lastname which is fine, but the e-mail address given, and the one that displays to recipients, is @comcast.net which I do not prefer. Any hints?

Thank you.

I think you would have to set up an email account in WLM with "<name>@pobox.com" as the email address shown as the email address on the "General" Tab. Then be sure you are "in" that account's set of folders when you "create mail" or use the "from" dropdown box to select it before sending.
