RE: Finding person name based on personnel email account

["Isaac Van Name" <ivanname () southerlandsleep com>]

If they're using Outlook to send the emails with the Yahoo account, then I'd
check your firewall logs for outbound traffic to a Yahoo mail server.  You
could also check the logs for HTTP access to Yahoo mail, if they're using
the website, and trace the source IP.

If all that fails (which it shouldn't),
http://answers.yahoo.com/question/index?qid=20061112180603AAMDySh

That site lists a few ways in which you can try to find a person's
information tied to their Yahoo account.

Of course, if they are using the website, I'd just set up a proxy server and
deny HTTP 
requests to mail.yahoo.com (or, rather, allow the few websites you will
allow, and deny everything else).  This is what we do here... just using a
computer with mediocre hardware, Linux (no GUI), and Squid.

Hope that helps.
