It seems that Yahoo doesn't fill in the information contained within mailto links like other mail clients do. I'm asking here to see if anyone knows a work-around for Yahoo.
Given this html:
<html>
<head></head>
<body>
<a href="mailto:me@somewhere.com?subject=Hello%20People&bcc=somebcc@example.com">Send Mail</a>
</body>
</head>
Can you successfully click the mailto link, Send Mail, and have yahoo open the webmail client AND fill in the meta data?
I am using the Chrome mailto extension to allow me to open webmail in my client of choice, and have selected Yahoo. So that part is working fine...
