Ok. When you click on a link on a website like Craigslist, it is a mailto:
link, and it should open your default email program.
If you prefer using Hotmail or Yahoo webmail, maybe the following links
may help.... (I can't vouch for them)

If you wish to use Windows Live Mail (WLM) and your Hotmail email account,
it's pretty simple.
Open Windows Live Mail.
Click on "Tools" - "Accounts" - "Add.."
Click on "Email account"
Click on "Next"
Enter your Hotmail email address and password in the correct boxes...
Enter your name as you would like it to be shown...
You won't need to enter any server names or settings..
Click on "Next"
Click on "Finish"
Now make sure that WLM is the default email program...
Click on the Vista "Start" button - "Default Programs" - "Set your default
programs".
highlight "Windows Mail", then click on "Choose defaults for this
program".
click on "Select all" to make sure the MAILTO is selected
click on "Save"
Now it should work.
