[Mailman-Users] Using Mailman without /etc/aliases

[Luke]

Hello all,

Our unix system here uses a kind of strange distributed aliases system-
running newaliases affects /etc/aliases on all machines.  So getting
mailman to work in the traditional sense wouldn't be acceptable at my
site. 

I do, however, have root access on my own machine.  So I could create a
mail spool, or even a user, for each mailing list I create (not many). 
Can anyone think of a way to get mailman to get the appropriate scripts to
execute for incoming mail by tricks with either the mail spool, the
.forward file, or something like that?  Let me know if anyone has any
ideas. 

Thanks
Luke Palmer
