No need for specific program. Information is already there
only look all headers. Every computer thought what e-mail
goes is written in Received: headers. Last one is usually
originating computer.  Spammers are start to add
fake Received: fields but usually it is not very hard identify
origin of e-mail.  Problems are when sender uses anonymous
remailer. Then only what You can do is contact Your ISP
and maybe also police.
