Your wording here is a little confusing.  Are you saying that several people are 
not only on the mailing list, but also in the 'staff' alias, which is also on 
the mailing list?

Sounds to me like your MTA is doing what you've told it:  when mail comes in for 
X, send a copy to   [A,B,C,D....].

One option you might consider (and one I'll be investigating once we migrate to 
1.0) is to have the list mails delivered to shared folders.  Then your only 
issues are new/read flags (which can be great for sales inquiry lists, btw) and 
who gets to delete messages.
