using telnet to send emails

That's not what I want. I know how to do that much. That will tell what email address the mail was sent from but not the person sending it.

You need to understand SMTP.  You can look at RFC821 here:
http://www.faqs.org/rfcs/rfc821.html

Here is a dialogue which does what you want:

csh> telnet mail.tic.com 25
Trying 68.14.224.76...
Connected to ns1.tic.com.
Escape character is '^]'.
