All the headers of the spam post. In a default installation, if any of
From:, Reply-To: or Sender: headers or the envelope sender as
reflected in the Unix From or Return-Path: header contains a member
address, the post will be deemed from that member.
Find the spam posts in archives/private/LISTNAME.mbox/LISTNAME.mbox.
The headers there should reflect the original except maybe for
Reply-To: if the list mungs that.
If that isn't the answer, then it is possible that, as Lindsay
suggests, the post contained an Approved: header with the list admin
or moderator password.
