How Can I Figure Out The Address To Which This Mail Was Sent?

I need help to find out what address some mail is being sent to.  

I am subscribed to a Bitnet conference.  I subscribed by sending a
command to a server known as a listserv.  The problem here is that these
listservs, because they are on Bitnet, will typically register Internet
users by an indirect address (e.g., westes%netcom.com@<bunch of stuff>...)

Recently I switched userids here on Netcom.  I asked the administrator
of the Bitnet conference to add my new userid and delete the old one,
since I know from hard experience that commands to a listserv to remove
an Internet user seldom manage to find the user's address (obviously a
bug in listserv).  The administrator could not find my old address.  And
so now I am getting two copies of every post...one sent to my new
address and one sent to my old address (which is now a mail alias for my
new address).

I thought it would easy enough to examine the RFC-822 header to see what
userid my name had been stored under and pass this on to the
administrator to delete.  Alas, the header of the mail that I received
does not seem to contain my address at all!  Clearly there is something
about distribution lists in RFC-822 that I do not understand.  

My question is: what can I do to determine the actual address to which
this mail is being sent?  The actual header is as follows:

 Short answer:  There is nothing you can do.

 Long answer: Well, if your postmaster cooperates, there is one possibility
you can try.  Ask your postmaster to temporarily modify 'sendmail.cf' so
that the aliasing is done in a rewrite rule instead of in the aliases file.
After the changes, the sendmail daemon will need to be killed and restarted.

 You will then be able to see the original recipient address in the syslog
records which are probably being recorded in /var/log/syslog.  This doesn't
work with normal aliasing, since then the syslog records contain the
original alias expansion.
