Depends on whether they submit the message using Yahoo's web form or
if they use Yahoo's SMTP servers (which require authentication).  If
the web interface is used, then no (the first IP address listed will
be one of Yahoo's mail servers).  If the SMTP server is used to submit
the message, then the first receive line should have their machines IP
address.

just by analysing the header of an email which was sent
with a free provider like Yah** ...

Thanks
