I tried this myself this afternoon.  Subscriber set to IETFHDR, listname
was in the BCC:, non-existent userid (valid hostname) in the TO:
field.  Mail was transmitted and the listname did NOT appear in the
TO:.  Mail did bounce from the non-existent TO:.  I could have sent it to
a real userid.

Depending upon your MTA, it may be that the listname will appear buried
in the RECEIVED headers (like it did on mine).
