How to send email from localhost to yahoo or gmail???

You need to install a mail server on your machine, if you don't have one. A lot of ISPs block outgoing port 25 though, so it might not be possible depending on your ISP.

Here's what I use in windows. It doesn't actually send it out to the email address, but it captures the sent email locally by monitoring the email ports and displays it in your email app as if it did. Very handy.
