The best way would be to ask who sent the email. Aside from that
option, there is no way to trace it from the copy you have in your
email inbox or even the copy that might still exist on your email
server, if you have access to that.

The BCC header is stripped by the mail server right before delivering
it, so it doesn't exist any longer. That's how sometimes you can get a
email message that isn't addressed to you.

A good page to read about email headers and other related issues is
here :

Hope this answers your question. Please feel free to ask for
clarification if required.

It's also extremely easy to forge e-mail headers, so even if an e-mail
says it is from a certain person you can't know with absolute
certainty (except with certain types of secure e-mail).

Sometimes you can check the headers of e-mail to find out the route it
took to get to you, and sometimes it might be possible to use this
info to track the sender down, especially if you have a subpoena that
would make the logs of the sender's ISP available.  So unless you're
prepared to go to court, you're usually out of luck finding out who
sent you anonymous e-mail (and even then you can't be assured you'll
find out what you want to know).

That answer is only actually correct in most circumstances.  ISPs
would have a log of who sent the e-mail and who they sent it to that
they would keep on file for some amount of time (it will vary at
different providers).  If the e-mail contains illigal subject matter,
it would be possible to get a warrant to check the sender.

Also, some mailing lists allow you to view the subscribers for the
different lists.  If the server runs majordomo, then you can send an
e-mail to majordomo@server.com with "who listname" in the body of the
message. The server could reply with a list of users in the list
unless it is configured to not send that information.

I hope that helps.
